Easy Tomato Basil Muffin Tin Frittata | Healthy Mini Frittatas for Breakfast

By Rebecca St.Clair

These Easy Tomato Basil Muffin Tin Frittata are one of those wonderfully simple recipes that can fit into almost any part of the day. They’re quick to prepare, naturally gluten-free, packed with eggs, fresh tomatoes, fragrant basil, and plenty of savoury flavour.

I especially love making mini frittatas in a muffin tin because they’re already perfectly portioned. You can make a batch on the weekend and have an easy breakfast ready for busy mornings, pack them into lunches, or serve them warm alongside a salad for a simple supper.

And because everything cooks together in the muffin tin, there’s very little fuss and hardly any dishes to wash. That’s my kind of breakfast!

What is a fritatta?

A frittata is an Italian egg dish that’s similar to a crustless quiche or an open-faced omelette.

Unlike a traditional omelette, a frittata isn’t folded over. Eggs are whisked with milk or cream and seasonings, then combined with vegetables, cheese, meat, or other ingredients and cooked until set.

A traditional frittata is usually made in a skillet or baking dish and sliced into wedges. A muffin tin frittata uses the same basic idea but turns the mixture into individual little portions.

This makes mini frittatas especially handy for meal prep.

You can serve a frittata:

• Hot for breakfast with hash browns
• Warm for brunch
• Cold for a picnic
• At room temperature for a potluck
• Alongside a green salad for a simple dinner

It’s one of those wonderfully flexible recipes that doesn’t really belong to just one meal.

Why Tomato and Basil Work So Well Together

Tomatoes and basil are a classic pairing for a reason.

The tomatoes bring sweetness and acidity, while fresh basil adds a fragrant, slightly peppery freshness. Add creamy eggs and melted cheese, and you’ve got a simple combination that tastes much more special than the ingredient list would suggest.

For the best tomato basil frittata, I recommend using sun dried tomatoes since this gives you a bold tomato flavour without any extra moisture. Im using fresh basil but dried will also work for this recipe.

Tips for Making Perfect Muffin Tin Frittatas

Cook watery vegetables first

This is probably the most important tip.

Ingredients such as tomatoes, zucchini, mushrooms, and spinach contain quite a bit of water. If you add them raw, that moisture can be released into the eggs as they bake.

For the best mini frittatas, cook moisture-rich vegetables first or drain and squeeze them well.

Don’t overfill the muffin cups

Fill the cups approximately ¾ full. The egg mixture will puff as it cooks.

Whisk the eggs thoroughly

Whisking the eggs and milk or cream thoroughly gives you a more evenly textured, creamy frittata.

Season the eggs before baking

Eggs need seasoning! Make sure the egg mixture is properly seasoned before pouring it over your fillings.

Don’t overbake

Overcooked eggs become dry and rubbery.

Remove the frittatas when the centres are just set. They’ll continue cooking from residual heat after coming out of the oven.

Let them rest

Give the frittatas a few minutes to cool before removing them from the pan. This allows the eggs to finish setting and makes them easier to handle.

Does the Muffin Tin Matter?

It actually can!

Different types of muffin tins conduct heat differently, which can affect how quickly your frittatas cook.

Metal muffin tin

A standard metal muffin tin heats relatively quickly and is a good choice for mini frittatas.

Cast iron muffin pan

Cast iron retains heat extremely well. Your eggs will continue cooking after the pan is removed from the oven.

If you’re using cast iron, keep a close eye on the frittatas and consider removing them when they’re just shy of completely set.

Silicone muffin cups

Silicone doesn’t conduct heat as quickly as metal, so your frittatas may take a little longer to cook.

Whatever pan you use, watch the eggs rather than relying entirely on the clock. The size and material of your pan can change the cooking time.

Can I Make These with Other Vegetables?

Absolutely!

That’s one of the best things about a muffin tin frittata recipe. Once you have the basic egg mixture, you can change the fillings depending on what’s in season or what’s waiting in the refrigerator.

Some delicious combinations include:

🥦 Broccoli & Cheddar

A classic combination that’s especially good for breakfast or lunch.

🍄 Spinach & Mushroom

Earthy mushrooms and tender spinach make a lovely savory frittata.

🥔 Potato, Ham, & Cheese

Perfect for a hearty breakfast. Use cooked potatoes or leftover roasted potatoes.

🌱 Asparagus, bacon, & Swiss Cheese

A beautiful springtime combination.

You can also add cooked bacon, sausage, ham, leftover roasted vegetables, or different varieties of cheese.

Is Tomato Basil Muffin Tin Frittata Gluten-Free?

Yes, this tomato basil muffin tin frittata is naturally gluten-free, provided the individual ingredients you’re using are gluten-free.

Frittatas don’t traditionally contain bread or a pastry crust, making them a wonderful naturally gluten-free breakfast option.

This is one of the reasons I love them so much. Unlike quiche or strata, there’s no crust or bread to prepare.

If you’re cooking for someone with celiac disease or a serious gluten allergy, always check packaged ingredients such as cheese, seasonings, and cooking products for gluten-containing additives or cross-contact warnings.

Are Tomato Basil Muffin Tin Frittata Healthy?

Frittatas can be a nutritious and satisfying meal, particularly when they’re made with eggs, vegetables, and a moderate amount of cheese.

Eggs provide protein, while vegetables add vitamins, minerals, and fibre.

You can easily make these healthy mini frittatas your own by adding extra vegetables and choosing the cheese and other fillings you enjoy.

They’re also filling enough to keep you satisfied without requiring a complicated breakfast.

Can You Make Tomato Basil Muffin Tin Frittata Ahead?

Absolutely! These are excellent make-ahead breakfasts.

Make a batch on the weekend, allow them to cool, and store them in an airtight container in the refrigerator.

They’ll be ready to grab on busy mornings when you don’t have time to cook breakfast from scratch.

They’re also lovely for:

• School lunches
• Work lunches
• Road trips
• Picnics
• Camping
• Brunch
• Meal prep

For best quality, enjoy refrigerated frittatas within 4 days.

How to Store Tomato Basil Muffin Tin Frittata

Allow the frittatas to cool completely before storing.

Place them in an airtight container and refrigerate for 3–4 days.

To reheat, microwave gently until warmed through. You can also reheat them in a low oven if you prefer.

Try not to overheat them, as this can make the eggs rubbery.

Can You Freeze Tomato Basil Muffin Tin Frittata?

Yes! Mini frittatas can be frozen, although the texture may change slightly after thawing.

To freeze:

1. Allow the cooked frittatas to cool completely.
2. Wrap them individually or place them in a freezer-safe airtight container.
3. Label and date the container.
4. Freeze for up to 3 months for best quality.

Thaw them overnight in the refrigerator and reheat gently.

Ingredients with a high water content, such as tomatoes and zucchini, may release a little more moisture after freezing and thawing. They will still be delicious, but the texture may be slightly softer.

Frequently Asked Questions

Why are my muffin tin frittatas watery?

The most common reason is excess moisture from vegetables. Tomatoes, zucchini, mushrooms, and frozen spinach can all release water while cooking. Cook or drain these ingredients before adding them to your eggs.

Why did my frittatas puff up and then fall?

That’s completely normal! Eggs puff as they cook and then naturally settle as they cool. It doesn’t mean anything went wrong.

How full should I fill the muffin cups?

About ¾ full is a good rule. This gives the eggs room to puff without overflowing.

Can I use milk instead of cream?

Yes. Milk works beautifully. Cream will give you a richer, slightly more luxurious texture, while milk produces a lighter frittata.

Can I make these without cheese?

Certainly. Cheese adds flavor and richness, but it isn’t essential. Add extra herbs or vegetables if you’d like.

Can I eat frittatas cold?

Yes! They’re delicious cold or at room temperature, which makes them especially useful for picnics, packed lunches, and meal prep.

What to Serve with Tomato Basil Muffin Tin Frittata

For breakfast, serve these little frittatas with:

• Crispy hash browns
• Toast
• Fresh fruit
• Sautéed potatoes
• Fresh tomatoes
• Avocado

For lunch or dinner, I love serving them alongside a simple green salad, crusty bread, or roasted vegetables.

And for brunch, arrange the frittatas on a large platter with fresh herbs and seasonal fruit. They look wonderfully inviting without requiring much fuss.

How to Make Tomato Basil Muffin Tin Frittata

1. Preheat oven to 350 °F (180 °C).

7. Whisk this until the egg mixture is smooth and creamy.

8. Into the greased muffin tin, evenly add the mix-ins.

9. Pour the egg mixture into each muffin cup, leaving a little bit of room at the top of each one.

10. Bake in the preheated oven for 20-25 minutes, or until set.

11. Remove from the oven and allow to cool.

12. Run a knife around each frittata to release the sides. Remove and serve or pack in an airtight container for meal prep.
