With pork sausage, cheese and peas, this easy frittata recipe is a real crowd pleaser!
Frittatas are a great fall back recipe for those nights when you just don’t know what to cook. They’re customisable, can be made in one pan, and are easy and delicious too.

They also don’t need any particular special equipment – just a good non stick pan – or ingredients, the base being egg.
Frittatas are often known as crustless quiches, and that’s a good way of seeing this recipe – it’s just like a sausage and cheese pie, without the pastry!

The Ingredients
- Sausages – this recipe calls for cooked sausages. You can either buy cooked sausages, use leftover cooked sausages from another recipe, or precook your sausages. You could fry, grill or bake them. You don’t need to leave them to cool before using; just cool them enough for you to be able to slice them safely.
- Peas – frozen peas are perfect here. They just need to be cooked long enough to defrost, then they cook through in the frittata. You can use fresh peas if you like.
- Eggs – the recipe calls for 7 or 8 medium/large eggs. The exact amount you need will depend on the size of your pan. Start with the lower number, and if you need more just whisk it up separately and pour it in. See the video for a guide about how much egg there should be.
- Cheddar and mozzarella– this frittata has two different types of cheese; cheddar is whisked into the egg mix and mozzarella is scattered on top. Try to use these cheeses if you can get hold of them, otherwise you can use cheddar throughout the recipe.
How to Cook Sausage and Cheese Frittata
Start by softening the onion in oil, then add sliced (cooked) sausages and frozen peas.

Whisk together the eggs and the cheddar cheese until the eggs are well combined.

Pour the egg mix into the saucepan and move around gently until it fills all the gaps between the sausage/pea mix. Cook gently for a minute or two.

Top with the mozzarella and put under the grill for 10-15 minutes until golden and set.

Cooking Tips
- Start on the hob, finish under the grill. This gives you a golden top and evenly cooked centre.
- Don’t rush the eggs. Keep the heat low so the base sets gently without burning.
- Use a non-stick pan. Makes it easy to lift out cleanly and avoids any sticking.
- Rest before slicing. Give it a minute or two to firm up once out of the grill – it’ll slice more neatly.
- Check your grill. Every grill’s different, so keep an eye to avoid over-browning.

Sausage and Cheese Frittata

Ingredients
- 1 tablespoon olive oil
- 1 onion
- 6 sausages good quality, cooked and sliced
- 250 grams frozen peas
- 7-8 eggs
- 50 grams cheddar cheese grated
- 50 grams mozzarella grated
Instructions
- Preheat your grill to high.
- Peel and finely chop the onion. Add the oil to a non stick frying pan and put on a medium heat. Add the onion and cook for 4-5 minutes until starting to soften.
- Add half of the sliced cooked sausages and the frozen peas. Cook, stirring frequently, until the peas have defrosted (approximately 3-4 minutes).
- Meanwhile, crack the eggs into a large bowl and add the cheddar cheese and a pinch of salt and pepper. Whisk until well combined.
- Pour the eggs evenly into the frying pan. Make sure all of the sausage and peas are covered by the egg. Move it around gently with your wooden spoon if you need to. Turn the heat down to low.
- Arrange the remaining sliced sausage in a circular pattern on top of the egg. Scatter the grated mozzarella evenly over the top.
- Transfer the frying pan to the grill and cook for another 10-15 minutes, until the egg has set and the mozzarella is melted and golden.
- Serve hot or cold with a side salad.

Variations
- Add vegetables: Sliced peppers, spinach, mushrooms or courgettes all work brilliantly.

- Add herbs: Chopped chives or parsley make it extra fresh.
Storage & Reheating
- Fridge: Keeps well for up to 3 days in an airtight container.
