Let me just sayโthis frittata nearly ended up scrambled eggs in disguise the first time I made it.
It was one of those Tuesday mornings where I thought, โOh, Iโve got 30 minutes and some wilting spinachโIโll just whip this up.โ Famous last words. I overcooked the bottom, forgot to season the eggs, and used a pan that wasnโt quite ovenproof. Disaster? Nearly. But I tweaked a few things (and learned to double-check the pan handle), and now itโs my go-to when I want something comforting, colourful, and packed with flavourโwithout feeling like Iโm making a full English.
The feta gives a lovely salty bite, the tomatoes roast just enough to pop, and itโs all tied together in golden, puffed-up egg. Let me show you what I changed to make it foolproof.
Why This One Works So Well
The magic here is the oven finish.
Lots of frittata recipes try to do everything on the stovetop, but that just leads to a burnt bottom and a wobbly top. By starting it on the hob and finishing in a hot oven, you get that golden, puffed top and an evenly set middle. No rubbery eggs. No soggy centres.
Plus, Maryโs combo of sweet peppers, garlic, and tangy feta hits that perfect savoury-sweet-salty trifecta. I didnโt expect such a short ingredient list to give this much flavour, but it does.
Ingredients + Why They Matter
- Sunflower Oil โ Neutral flavour and high smoke point. I tried olive oil once and the eggs browned too fast.
- Onion (thinly sliced) โ Brings sweetness and depth. Donโt skip the full sautรฉโit makes a difference.
- Red Pepper โ Adds crunch and colour. I once used yellow, and it was fineโbut red is sweeter.
- Garlic โ Just one clove, but it rounds everything out. Too much and it overpowers.
- Baby Spinach โ Softens quickly and adds a bit of โgreen virtueโ to your brunch.
- Eggs (8 large) โ The structure and the star. Beat them well, and season properly.
- Feta (crumbled) โ Salty, creamy, doesnโt melt completely, which I love. Goatโs cheese didnโt work as wellโtoo runny.
- Cherry Tomatoes โ Bursts of sweet acidity. Quarter them if theyโre on the big side.
Making It Yours (Without Ruining It)
- No Feta? Use crumbled goatโs cheeseย onlyย if you like a creamier textureโitโs a bit messier.
- Dairy-Free? Omit the cheese and add a few spoons of cooked, diced sweet potato for body.
- Veggie Swaps: Cooked courgette or mushrooms can replace the red pepper, but be sure to cook off the water.
- Egg-Free? Honestly, I havenโt cracked that yetโthis oneย reallyย depends on eggs to hold its shape.
Mistakes Iโve Made (And How to Avoid Them)
What Went Wrong | Why It Happens | How to Fix It |
---|---|---|
Rubbery texture | Overbaked it by 5+ minutes | Check at 10 minutes. Knife should come out clean. |
Bottom stuck to the pan | Used a non-stick that was worn | Grease well and check your panโs coating |
Spinach was soggy | Didnโt wilt it down first | Always sautรฉ spinach until just wilted |
How To Make Mary Berryโs Frittata
- Preheat oven to 200ยฐC (180ยฐC fan) / Gas 6. Make sure your frying pan isย trulyย oven-safeโI use a 26cm non-stick with a metal handle.
- Sautรฉ onion and red pepper in sunflower oil for 10 minutes. Take your timeโthey should be soft, not just warmed through.
- Add garlic and spinach, and cook until the spinach wilts (about 2โ3 minutes). Donโt skip this or youโll have puddles later.
- Beat the eggs in a jug with a good pinch of salt and pepper. I use a fork, not a whisk, so I donโt add too much air.
- Pour eggs into the pan, swirling to coat. Let it cook gently for 3โ4 minutesโedges should look set.
- Scatter over feta and tomatoes evenly.
- Transfer to oven and bake for 10โ15 minutes. It should puff slightly and look golden on top.
- Cool slightly, then loosen the edges and slide onto a board or plate. Slice into wedges.

Tips From My Kitchen
- I sometimes add a pinch of dried oregano for a Greek-ish twist.
- If your oven runs hot (like mine), check it at 10 minutesโit cooks fast.
- Quartering the tomatoes helps stop them making soggy patches.
- Let it cool for 5 mins before slicingโit sets better.
Storage + Serving
- Fridge:ย Keeps 3 days in a sealed container.
- Freezer:ย I donโt recommend freezingโtexture goes odd.
- Reheat:ย Oven (180ยฐC for 10 mins) or stovetop with a lid. Microwave works, but dries out quickly.
- Serve With:ย A lemony green salad, sourdough toast, orโif youโre like meโcold with hot sauce straight from the fridge.
FAQs
Q: Can I make this ahead of time?
A: Absolutely. Bake it the night before and reheat gently in the oven or have it coldโstill tasty.
Q: Do I have to use feta?
A: Itโs best with feta, but mild goatโs cheese or even diced halloumi work. Just avoid soft cheesesโthey melt too much.
Q: How do I stop the eggs going rubbery?
A: Donโt overbake! Check at 10 minutes. The centre should just setโlike a firm custard.
Q: Can I add meat?
A: Yepโcooked bacon or sausage works well, but keep the quantity small so it doesnโt overpower the veg.
Q: Whatโs the best pan to use?
A: A non-stick, oven-safe frying pan, 26cm across. Avoid anything with plastic or wooden handles.
