Ingredients

Makes 6 individual frittatas | Preparation time: 15 minutes | Cooking time: 25–30 minutes

• 300g cauliflower florets, cut into small bite-sized pieces
• 1 tablespoon olive oil
• 6 large eggs
• 100g Open Air Cheddar, grated
• 2 tablespoons milk
• 1 small garlic clove, finely grated or crushed (optional)

Cheese tip: Open Air Cheddar is a lovely choice for this recipe. Its full, savoury Cheddar flavour pairs beautifully with the sweetness of roasted cauliflower. Grate it fresh for the best texture and an even distribution through each frittata.

How to Make Roasted Cauliflower Cheese Frittatas

Step 1: Roast the cauliflower

Preheat your oven to 200°C (180°C fan) / 400°F / Gas Mark 6.

Place the cauliflower florets on a baking tray, drizzle with olive oil and season with a little salt and plenty of freshly cracked black pepper. Toss to coat, then spread the cauliflower out in a single layer.

Roast for 15–20 minutes, turning once, until the florets are tender and beginning to turn golden around the edges. Set aside to cool slightly.

Roasting the cauliflower before adding it to the eggs is worth the extra few minutes. It helps prevent the frittatas from becoming watery and gives them a lovely depth of flavour.

Step 2: Prepare the egg mixture

Reduce the oven temperature to 180°C (160°C fan) / 350°F / Gas Mark 4.

Lightly grease a six-hole muffin tin. In a large bowl, whisk together the eggs and milk until combined. Stir in the grated Open Air Cheddar, thyme and garlic, if using. Season generously with black pepper and add a small pinch of salt.

Remember that the Cheddar will bring its own savoury flavour, so you don't need too much extra salt.

Step 3: Assemble the frittatas

Divide the roasted cauliflower between the six muffin holes. Pour the egg mixture evenly over the top, allowing it to settle around the florets.

Give each one a gentle stir with a teaspoon to distribute the cheese and cauliflower. Finish with a little extra grated Cheddar and a few thyme leaves.

Step 4: Bake until golden

Bake for 15–20 minutes, or until the frittatas are puffed up, lightly golden and set in the centre. Cooking time will depend on the size of your muffin tin, so check that the egg mixture is fully cooked through before removing them from the oven.

Leave to rest in the tin for five minutes, then carefully loosen the edges and lift them out.

Step 5: Serve and enjoy

Finish with another twist of black pepper and serve warm, or allow the frittatas to cool for an easy lunch later on.

The combination of sweet roasted cauliflower, tender egg and rich Open Air Cheddar makes these little frittatas wonderfully satisfying without needing a long list of ingredients.

Tips for the Best Cauliflower Cheese Frittatas

Cut the cauliflower into small florets. Smaller pieces distribute more evenly through the egg mixture and make the frittatas easier to eat.

Don't skip roasting. Raw cauliflower releases moisture as it cooks. Roasting it first helps concentrate its flavour and gives the finished frittatas a better texture.

Grate your Cheddar fresh. Freshly grated cheese melts evenly and gives you cheesy flavour in every bite.

Be generous with black pepper. The gentle heat of freshly cracked black pepper balances the richness of the Cheddar and eggs beautifully.

Avoid overbaking. Once the eggs are set, remove the frittatas from the oven. Leaving them in too long can make them firm and dry.

Let them rest before removing. A few minutes in the tin helps the frittatas hold their shape.

Easy Variations

Once you’ve tried the basic recipe, it’s easy to make these roasted cauliflower frittatas your own.

• Cauliflower and broccoli: Replace half the cauliflower with roasted broccoli florets.
• Cheddar and spring onion: Add two finely sliced spring onions to the egg mixture for a fresh, savoury flavour.
• Smoky paprika: Sprinkle a little smoked paprika over the cauliflower before roasting.
• Spinach and Cheddar: Stir a small handful of wilted spinach into the egg mixture, squeezing out any excess water first.
• Herby frittatas: Swap the thyme for chopped chives or parsley.

Keep the balance of egg, vegetables and cheese similar so the frittatas set properly.

What to Serve with Cauliflower Cheese Frittatas

These little frittatas are delicious on their own, but they're even better with a few simple accompaniments.

For an easy lunch, serve with a crisp green salad dressed with olive oil and lemon. For brunch, add buttered toast, roasted tomatoes or sautéed mushrooms. They also make a lovely addition to a picnic spread or lunchbox.

If you're preparing a few dishes for a relaxed lunch with friends, serve them alongside a bowl of seasonal salad and some crusty bread.

Can You Make Cauliflower Cheese Frittatas Ahead?

Yes. These frittatas are ideal for making ahead.

Allow them to cool promptly, then store them in an airtight container in the fridge. Keep refrigerated and eat within 2 days. They can be enjoyed cold straight from the fridge or reheated until piping hot throughout.

For the best texture, avoid leaving them at room temperature for extended periods. If taking them on a picnic or to work, keep them chilled until you're ready to eat.

A Simple Recipe Made Better with Good Cheese

The best recipes don't always need complicated techniques or a cupboard full of ingredients. Sometimes, a few carefully chosen ingredients make all the difference.

In these roasted cauliflower cheese frittatas, roasting brings out the sweetness of the cauliflower, while Open Air Cheddar delivers the savoury, cheesy flavour that makes every bite worth looking forward to.

Make them for an easy lunch, prepare a batch for the week ahead, or serve them as part of a leisurely weekend brunch. However you enjoy them, they're a simple reminder that good cheese can turn everyday cooking into something special.
