Mini Ovens Reviewed
1. HOMCOM 9L Mini Oven Countertop Electric Grill 750W – Black
Best for: Single-person households, students, or anyone who needs a compact mini oven that takes up as little worktop space as possible.
At 9 litres, this is the most compact oven on this list and the most affordable starting point for countertop cooking. The 750W power keeps running costs low, and the adjustable temperature and timer allow basic baking, grilling, and toasting without the complexity of larger appliances. It is the right choice when worktop space is genuinely limited, in a studio flat, a compact kitchen, a home office, or a room without a full kitchen setup.
The 9L capacity fits a small roasting dish, two slices of toast, or a portion of chips, practical for quick everyday meals rather than batch cooking.
Key Features:
- Black finish suits most kitchen colour schemes.
- Baking tray included.
- Dial controls, straightforward operation with no digital setup required.
Pros:
- Smallest footprint of any oven on this list, maximises limited worktop space.
- 750W keeps electricity costs down for daily use.
- Straightforward dial controls, no digital learning curve.
Cons:
- 9L capacity limits batch cooking, not suited to cooking for more than one person at a time.
- 750W means longer preheat time compared to higher-wattage alternatives.
2. HOMCOM 15L Convection Mini Electric Oven and Grill – Cream White
Best for: Everyday home cooking for one to two people who want convection heat distribution for more even results.
The convection fan is what sets this oven apart from a basic countertop grill. Convection circulates hot air evenly around the food, reducing hot spots, cutting cooking time, and producing a more consistently cooked result than a static heating element alone. At 15 litres it comfortably fits a small roasting dish, a half-sized baking tray, or a whole chicken portion for one. The temperature range of 60°C to 230°C and the 60-minute timer cover everything from slow warming to full roasting.
The cream white finish suits kitchens with a retro or neutral palette where black would clash.
Key Features:
- 1000W rated power.
- The grill element and convection fan operate independently or together.
- Wire rack and baking tray included.
Pros:
- Convection fans produce more even cooking results than static oven alternatives at the same price.
- 60°C minimum temperature allows gentle warming and cooking as well as cooking.
- Cream white finish offers a visual alternative to the predominantly black and silver options in this category.
Cons:
- 15L capacity is comfortable for one person but tight for two simultaneously.
- Convection fans can be slightly noisier during operation than static alternatives.
3. HOMCOM 16L 1400W Countertop Mini Oven with Crumb Tray – Black
Best for: Kitchens where higher wattage cooking performance and easy cleaning matter more than compact size.
The step up from 750W to 1400W makes a meaningful practical difference, faster preheat, more consistent temperature maintenance during cooking, and better performance for grilling where heat recovery after opening the door matters. The crumb tray collects crumbs and food debris from the oven floor without requiring the oven to be cleaned out after every session, a genuinely practical daily maintenance advantage at this usage level. At 16L the capacity handles most single or two-person meals comfortably.
Key Features:
- 4.7 verified buyer rating, one of the strongest-rated models on this list.
- Two heating elements, upper and lower, for flexible heat positioning.
- 60-minute timer with auto shut-off.
Pros:
- 1400W preheats and recovers temperature faster than lower-wattage alternatives.
- Crumb tray removed separately for cleaning, reduces time spent maintaining the oven interior.
- Two heating elements allow adjustment between top-down grilling and full surround heat.
Cons:
- Higher wattage draws more electricity per session than compact alternatives.
- 16L is a step up from smaller models but still not suitable for large batch cooking.
4. HOMCOM 28L Mini Oven with 2 Hot Plates Countertop Cooker – Black
Best for: Studio flats, bedsits, caravans, and any space where a full kitchen hob and oven are not available.
The two built-in hot plates are what make this a genuinely different product from everything else on this list. Rather than just an oven, this is a complete countertop kitchen in one unit, you can boil pasta on the top plates while roasting vegetables in the 28L oven below. For anyone living in a room without a kitchen, in a caravan, or in temporary accommodation, this effectively replaces a conventional cooker entirely.
Key Features:
- The only model on this list that allows simultaneous hob and oven cooking.
- Largest standard oven capacity on this list at 28L.
- Two hob plates and an oven operated from a single power connection.
Pros:
- Covers both hob and oven cooking, replaces a conventional cooker in spaces where none is available.
- 28L capacity handles full meal preparation for two people simultaneously.
- Hob plates heat independently from the oven, flexible control over which functions are active.
Cons:
- The largest footprint on this list, needs significantly more worktop space than compact alternatives.
- Higher power draw when both hot plates and the oven run simultaneously.
5. HOMCOM 10L Air Fryer Oven with Touch Screen – Black
Best for: Anyone who wants oil-free cooking results in a compact format with intuitive touch controls.
An air fryer oven works differently to a standard countertop oven. A powerful fan circulates hot air at high speed around the food, achieving the browning and crispness that normally requires deep frying, using little to no oil. This 10L HOMCOM model combines that air fryer function with a full touch screen interface, temperature and timer adjustments happen via the screen rather than physical dials, which suits buyers who prefer a cleaner, more digital control experience.
Key Features:
- High-speed convection fan produces crispy results using little or no oil.
- Black finish, compact footprint suited to limited worktop space.
- Removable drip tray for easy cleaning after air frying.
Pros:
- The air fryer function achieves crisp, browned results without oil, healthier cooking outcome.
- Touch screen interface is more precise for temperature setting than analogue dial alternatives.
- Compact 10L size gives air fryer capability without the footprint of a full standalone air fryer unit.
Cons:
- 10L is limited for cooking multiple items or larger portions simultaneously.
- Touch screens require more care when cleaning than wipe-clean dial alternatives.
6. HOMCOM 24L Air Fryer Oven with Touch Screen – Silver
Best for: Households of two to four who want air fryer cooking at a capacity that handles full meals rather than single portions.
The step from 10L to 24L is significant for air fryer cooking, it moves from a single-portion appliance to one that handles a whole tray of chips, a full chicken breast, or multiple portions simultaneously. The touch screen interface and oil-free air frying carry across from the compact model, but the larger chamber allows rack positioning, letting you cook at different heights for different food types in a single session.
The silver finish is also a practical alternative for kitchens where black appliances already dominate the worktop.
Key Features:
- Multiple rack positions, flexible simultaneous multi-level cooking.
- Silver finish, visually distinct from the black and cream alternatives on this list.
- The larger interior allows a full-sized baking tray or whole chicken.
Pros:
- 24L capacity makes this the right air fryer oven for cooking full family portions rather than individual servings.
- Rack positioning allows simultaneous cooking at different levels, useful for meal preparation.
- Silver finish distinguishes it from the predominantly black alternatives on this list.
Cons:
- Larger footprint than the 10L model, requires more dedicated worktop space.
- Higher wattage at this capacity draws more electricity per session than compact alternatives.
7. HOMCOM 3-in-1 Mini Oven, Long Slot Toaster and Grill 1700W – Stainless Steel
Best for: Buyers who want to replace three separate small appliances, a toaster, a countertop oven, and a tabletop grill, with a single integrated unit.
The long-slot toaster integrated into this 3-in-1 unit is what makes it completely unlike any other product on this list. Most mini ovens can perform basic toast as a function, but this model includes a dedicated long-slot toaster on top of the unit, capable of handling longer bread slices, baguettes, and thicker artisan bread that standard toaster slots cannot accommodate.
Alongside the oven and tabletop grill functions, this covers the three most common countertop cooking tasks in one stainless steel appliance with an LED display for precise control. At 1700W it is the highest-powered appliance on this list, delivering rapid preheat and fast toasting performance.
Key Features:
- 60-minute timer shared across all three cooking functions.
- Crumb tray included for all three modes.
- Three functions operated from a single plug point.
Pros:
- Replaces three separate appliances, oven, toaster, and grill, in one countertop unit.
- Long-slot toaster handles bread that standard toaster slots cannot, adding genuine versatility.
- LED display provides more precise control than analogue dial alternatives.
Cons:
- 1700W means the highest electricity draw of any appliance on this list.
- Three functions cannot all be used simultaneously, choose one mode at a time.
How Do I Choose the Right Mini Oven?
What size mini oven do I need?
- 1 person, light use: 9–10L suits toasting and basic grilling.
- 1–2 people, everyday cooking: 15–16L handles most daily meals.
- 2–3 people, full meals: 24–28L gives enough capacity for proper meal prep.
- Replacing multiple appliances: Size matters less than function; choose the 3-in-1.
Is a mini oven cheaper to run than a full-size oven?
A 750W mini oven uses roughly 30–40% of the energy a standard full-size oven draws, a meaningful saving for one or two portions daily. A 1700W model closes that gap, so wattage matters as much as size when considering running costs.
Mini oven vs air fryer oven, what is the difference?
A standard mini oven uses radiant heat from heating elements. An air fryer oven adds a powerful fan that circulates hot air rapidly, producing crispy, browned results with little or no oil. The trade-off is slightly more noise and the need to adjust conventional recipe timings.
Can a mini oven replace a full-size oven?
For one to two people, yes, for everyday roasting, baking, grilling, and toasting. Where mini ovens fall short is batch cooking, large cakes requiring even heat across a full-size tray, and dishes needing different temperatures simultaneously.
Quick Checklist: Before You Buy a Mini Oven
✅ Measure your worktop space, check both the footprint and clearance needed above and behind the unit for ventilation.
✅ Count how many people you regularly cook for, this determines the capacity you need.
✅ Decide on controls, dial controls are simpler and easier to clean; touch screens are more precise.
✅ Check the wattage, higher wattage means faster cooking but higher energy draw per session.
✅ Decide if air frying matters, if crispy oil-free results are a priority, choose an air fryer oven model.
✅ Consider whether hob plates matter, if you have no hob, the 28L model with two hot plates is the only appliance on this list that covers both cooking methods.
✅ Check what accessories are included, baking trays, wire racks, and crumb trays vary by model.

FAQs
1. What is a mini oven good for?
A mini oven is ideal for toasting, grilling, baking small portions and roasting for one or two people. It heats faster than a full-size oven and can use less energy for smaller meals. It is useful in compact kitchens, student accommodation, caravans and as a secondary appliance.
2. Are mini ovens safe to leave unattended?
Most mini ovens have a built-in timer with automatic shut-off, which turns the appliance off when the set time ends. However, you should not leave any heated appliance unattended, especially when grilling. Ensure good ventilation and keep the area clear of flammable materials.
3. Can you bake in a mini oven?
Yes, most mini ovens can bake cakes, muffins, biscuits and bread when you use suitably sized baking tins. However, their smaller interiors may distribute heat less evenly than a full-size oven. A convection model can help by using a fan to circulate hot air more evenly around the food.
4. How do I clean a mini oven?
Allow the oven to cool completely before cleaning. Remove the racks and baking trays and wash them separately with warm soapy water. Wipe the interior with a damp cloth and mild cleaner, avoiding abrasive scrubbers. Empty the crumb tray regularly and wipe the exterior with a damp cloth.
5. What wattage mini oven should I buy?
For basic toasting and light cooking, 750W can be sufficient and may help keep energy use lower. For faster cooking and stronger grilling performance, 1400W or above is more effective. A 1700W 3-in-1 model suits buyers who want faster, consistent results across several cooking functions.
