Frittatas are the unsung heroes of egg dishes for dinner and breakfast alike.

Why This Frittata Recipe Works
The secret to this frittata’s success lies in its simplicity. By browning the sausage first in a quality frying pan, you develop deep, caramelized flavors that infuse every bite. The eggs create a fluffy, custard-like texture that holds everything together beautifully. Fresh tomatoes release their juices during baking, keeping the frittata moist without making it soggy.
This recipe is incredibly versatile too. While it’s fantastic as written, you can easily adapt it to create a veggie frittata by swapping the sausage for mushrooms and bell peppers, or turn it into a bacon frittata by using crispy bacon instead. For those watching carbs, it’s already perfect as a keto frittata recipe with zero added sugars or starches.
What Makes This Different from Other Frittata Recipes
- No milk or cream needed – The eggs alone create incredible richness
- Single pan cooking – Less cleanup means more time enjoying your meal
- Foolproof technique – Starting on the stovetop then finishing in the oven ensures even cooking
- Meal prep friendly – Makes great leftovers for up to 4 days
Essential Ingredients
| Ingredient | Amount | Purpose |
|---|---|---|
| Breakfast sausage | 1 pound | Provides savory protein base |
| Eggs | 12 large | Creates fluffy, custard-like texture |
| Tomatoes | 3-4 medium | Adds freshness and moisture |
| Fennel seeds | 1½ teaspoons | Brings Italian-inspired flavor |
| Salt | ½ teaspoon | Enhances all flavors |
| Pepper | ¼ teaspoon | Adds subtle heat |
Ingredient Tips
Choose a good quality breakfast sausage with herbs and spices you enjoy. Italian sausage works wonderfully here, but maple sausage adds a sweet-savory twist. For the tomatoes, Roma or plum varieties hold up best during baking without releasing too much liquid.
Make sure your eggs are fresh and at room temperature for the fluffiest results. You can crack them into a mixing bowl about 30 minutes before cooking to take the chill off.
Kitchen Equipment You’ll Need
Having the right tools makes this recipe even easier:
- Oven-safe frying pan (10-12 inch cast iron or stainless steel)
- Mixing bowl for beating eggs
- Kitchen utensils including spatula and whisk
- Chef’s knife for slicing tomatoes
- Cutting board for prep work
Step-by-Step Instructions
Preparing Your Ingredients
Start by preheating your oven to 350°F. This ensures it’s ready when you need it. While the oven heats, slice your tomatoes into rounds about ¼-inch thick using a sharp chef’s knife. Set them aside on your cutting board.
Crack all 12 eggs into a mixing bowl and beat them lightly with a whisk or fork. You don’t need to whip them into a frenzy – just break the yolks and mix until combined. This creates the perfect texture without making the frittata too airy.
Cooking the Sausage
Place your ovenproof frying pan over medium-high heat. Add the breakfast sausage, breaking it up with a spatula from your kitchen utensils set. Let it brown for 10 to 15 minutes, stirring occasionally. You want it crispy and deeply browned – this is where all that delicious flavor develops.
Once the sausage is cooked through and crispy, carefully drain off the excess grease. Leave just a thin coating on the bottom of the pan to prevent sticking. Too much grease will make your frittata greasy, while too little causes it to stick.
Combining Eggs and Sausage
Reduce your heat to medium and pour the beaten eggs over the browned sausage. Using your spatula, gently stir the mixture together. You’re not scrambling the eggs – just distributing the sausage evenly throughout. Continue stirring gently for about 4 minutes until you see the edges of the eggs just starting to set.
This stovetop step is crucial. It gives the bottom of your frittata a head start on cooking, which prevents a soggy bottom when you transfer it to the oven.
Adding Tomatoes and Seasonings
Arrange your tomato slices evenly across the top of the partially cooked eggs. They should cover most of the surface in a single layer. Sprinkle the fennel seeds, salt, and pepper over the tomatoes. The fennel seeds will toast slightly in the oven, releasing their aromatic oils.
Baking to Perfection
Carefully transfer your pan to the preheated oven. Bake for 25 minutes. You’ll know it’s done when the center doesn’t jiggle when you gently shake the pan. The top should be lightly golden and the eggs should be completely set.
Remove from the oven and let the frittata rest for 5 minutes before slicing. This resting time allows the eggs to finish setting and makes slicing much cleaner.

Serving Suggestions
This Sausage Tomato Frittata shines on its own, but it’s even better with a few simple accompaniments. Serve it for breakfast with buttery toast and fresh fruit. For lunch or dinner, pair it with a crisp green salad and crusty bread.
Cut it into wedges like a pie for an elegant brunch presentation, or slice it into squares for easier serving at potlucks. It’s fantastic hot from the oven, at room temperature, or even cold the next day.
Make It Your Own
Once you’ve mastered this basic recipe, experiment with variations:
- Add cheese – Sprinkle shredded cheddar, mozzarella, or feta over the top before baking
- Swap proteins – Try bacon, ham, or keep it vegetarian with mushrooms
- Load up veggies – Add spinach, bell peppers, or onions to the sausage mixture
- Go spicy – Use hot Italian sausage and add red pepper flakes
Storage and Reheating
Store leftover frittata in an airtight container in the refrigerator for up to 4 days. To reheat, warm individual slices in the microwave for 30-45 seconds, or reheat the whole frittata in a 300°F oven for 10-15 minutes until warmed through.
This frittata also freezes beautifully. Cut it into individual portions, wrap each piece in plastic wrap, then store in a freezer bag for up to 3 months. Thaw overnight in the refrigerator before reheating.
Nutrition Benefits
This protein-packed frittata provides sustained energy throughout your day. Each serving delivers approximately 25 grams of protein from the eggs and sausage, making it perfect for those following high-protein or keto frittata recipes. The eggs provide essential vitamins like B12, D, and choline, while tomatoes add vitamin C and lycopene.
Frequently Asked Questions
Can I make this frittata ahead of time?
Absolutely! This frittata is perfect for meal prep. Cook it completely, let it cool, then refrigerate. It tastes great reheated or even served cold.
What if I don’t have an oven-safe pan?
You can start the frittata in a regular pan, then transfer it to a greased baking dish before adding the tomatoes and moving to the oven.
Can I use egg whites only?
Yes, you can make egg white frittata recipes using this same method. Use 24 egg whites in place of the 12 whole eggs. The texture will be slightly less rich but still delicious.
How do I know when the frittata is done?
The center should be set and not jiggly when you gently shake the pan. A knife inserted in the center should come out clean.
Can I add other vegetables?
Definitely! Just make sure to sauté any raw vegetables with the sausage first to remove excess moisture. Pre-cooked vegetables can be added directly with the eggs.
What’s the difference between a frittata and a quiche?
A quiche has a pastry crust and uses cream or milk in the egg mixture. Frittatas are crustless and typically use just eggs, making them lower in carbs and easier to prepare.
Can I make mini frittata recipes with this?
Yes! Divide the mixture among greased muffin tins and reduce the baking time to 12-15 minutes. This creates perfect mini frittata recipes for grab-and-go breakfasts.
Is this suitable for a vegan frittata?
This specific recipe uses eggs and sausage, but you can create a vegan frittata by using chickpea flour and plant-based sausage alternatives.
Tips for the Perfect Frittata
- Use a well-seasoned cast iron or non-stick pan to prevent sticking
- Don’t overcook – Remove from oven when center is just set
- Let it rest – Those 5 minutes make slicing much easier
- Choose fresh eggs – They create the fluffiest texture
- Drain your sausage well – Too much grease makes the frittata heavy
This Sausage Tomato Frittata proves that simple ingredients can create extraordinary meals. Whether you’re feeding a crowd at brunch, meal prepping for the week, or just craving a satisfying egg dish for dinner, this recipe delivers every single time. The combination of crispy sausage, fluffy eggs, and bright tomatoes creates a harmony of flavors and textures that keeps you coming back for more.
