Cheesy Sausage and Asparagus Frittata

Here is my favorite sausage and asparagus frittata recipe, packed with savory pork sausage, fresh vegetables, plenty of melted cheese, and a creamy egg mixture that’s perfect for breakfast or brunch.

This frittata is my go-to recipe when I need to feed my family something filling and delicious without spending all morning in the kitchen. I love that you can throw in whatever vegetables you have on hand, and it still turns out great every time.

What Kind of Sausage Should I Use?

You’ve got plenty of options when it comes to choosing sausage for this frittata. Italian sausage is a popular choice – you can go with sweet or spicy depending on your preference, and both will add great flavor to the dish. Breakfast sausage also works really well here and gives you that classic morning meal vibe. If you’re looking for a lighter option, chicken or turkey sausage will do the trick without sacrificing too much flavor. Just make sure to remove the casings if you’re using link sausage, and crumble it up as it cooks so it distributes evenly throughout your frittata.

Options for Substitutions

This frittata is super forgiving and works well with different ingredients you might have on hand:

• Sausage: You can swap the sausage for bacon, ham, or even ground turkey if you want something lighter. Vegetarians can skip the meat entirely or use plant-based sausage crumbles.
• Milk: Heavy cream makes the frittata richer, while half-and-half is a nice middle ground. You can also use unsweetened almond milk or oat milk if you’re avoiding dairy.
• Asparagus: Broccoli florets, zucchini, or bell peppers work great here. Just chop them into bite-sized pieces and cook them the same way you would the asparagus.
• Mushrooms: Any mushroom variety works – button, cremini, or shiitake all bring their own flavor. If you’re not a mushroom fan, just leave them out or add more vegetables instead.
• Cheddar jack cheese: Feel free to use whatever cheese you have – mozzarella, gruyere, feta, or goat cheese all taste great in frittatas. Just stick with something that melts well.
• Spinach: Kale, arugula, or Swiss chard can replace spinach. If using kale, chop it finely and give it an extra minute to cook down since it’s tougher than spinach.

Watch Out for These Mistakes While Cooking

The biggest mistake when making frittata is overbaking it, which leads to a rubbery, dry texture – pull it from the oven when the center still has a slight jiggle, as it will continue cooking from residual heat and firm up perfectly.

Another common error is adding watery vegetables without cooking them first, so make sure to cook your mushrooms and spinach until their moisture evaporates, otherwise you’ll end up with a soggy frittata.

Don’t skip greasing your baking dish well with butter or oil, because even with cheese in the mix, frittatas have a tendency to stick and you’ll lose half your breakfast trying to serve it.

Finally, resist the urge to add too much milk to your egg mixture – a 6:1 ratio of eggs to milk keeps things custardy without making it watery, and always whisk your eggs thoroughly to avoid streaks of egg white in the final dish.

What to Serve With Sausage and Asparagus Frittata?

A frittata is perfect for any meal of the day, so I like to keep the sides simple and fresh. For breakfast or brunch, serve it with buttered toast or a toasted English muffin and some fresh fruit like berries or melon slices. If you’re having it for lunch or dinner, a light arugula salad with lemon vinaigrette pairs really nicely with the rich, cheesy eggs. You could also add some crispy hash browns or roasted potatoes on the side to make it more filling.

Storage Instructions

Store: Leftover frittata keeps really well in the fridge for up to 4 days. Just let it cool completely, then cover it tightly with plastic wrap or store it in an airtight container. I actually think frittata tastes great cold straight from the fridge, but you can definitely warm it up if you prefer.

Freeze: You can freeze individual slices of frittata for easy breakfasts later. Wrap each piece in plastic wrap, then place them all in a freezer bag for up to 2 months. This is one of my favorite make-ahead breakfast options!

Reheat: Warm up your frittata in the microwave for about 30-45 seconds, or pop it in a 350°F oven for 10 minutes until heated through. If you’re reheating from frozen, let it thaw in the fridge overnight first for the best results.

• Calories: 1050-1200
• Protein: 60-70 g
• Fat: 75-85 g
• Carbohydrates: 16-22 g

Ingredients

For the filling:

• 0.6 lb sausage (I prefer Jimmy Dean ground pork sausage for the seasoning)
• 4 mushrooms (sliced into 1/4-inch pieces)
• 10 asparagus spears (tough ends removed and cut into 1-inch lengths)
• 1 handful spinach
• 1.25 cups cheddar jack cheese (freshly shredded for better melting and texture)

For the egg mixture:

• 6 eggs
• 1 cup milk (I use Fairlife whole milk to make it extra creamy and rich)
• 1/4 teaspoon garlic powder
• salt
• pepper

Step 1: Prepare the Oven and Mise en Place

• 4 mushrooms
• 10 asparagus spears
• 1 handful spinach
• 1.25 cups cheddar jack cheese

Preheat your oven to 350°F and lightly grease a 9×13 inch baking dish or similar size with butter or cooking spray.

While the oven heats, prepare all your ingredients: slice the mushrooms into 1/4-inch pieces, remove the tough ends from the asparagus spears and cut them into 1-inch lengths (separating and reserving the tender tips for garnish), and measure out your spinach and shredded cheese.

Having everything prepped and ready will make the cooking process smooth and efficient.

Step 2: Cook the Sausage and Vegetables

• 0.6 lb sausage
• 10 asparagus spears
• 4 mushrooms
• 1 handful spinach

In a large skillet over medium-high heat, cook the ground sausage, breaking it into small crumbles as it cooks, until it’s browned and cooked through (about 5-7 minutes).

Remove the sausage to a plate, then in the same skillet add the asparagus pieces and cook for 1-2 minutes until they begin to soften.

Add the sliced mushrooms and cook for another 2-3 minutes until they release their moisture and start to brown.

Finally, add the spinach and stir until completely wilted, about 1 minute.

I like to cook everything in the same pan to build flavor from the browned bits left behind by each ingredient—it’s a subtle touch that adds depth.

Step 3: Layer the Filling and Cheese

• cooked sausage from Step 2
• cooked vegetables from Step 2
• 1.25 cups cheddar jack cheese

Transfer the cooked sausage and all the cooked vegetables from Step 2 to your prepared baking dish, spreading them evenly across the bottom.

Sprinkle the freshly shredded cheddar jack cheese evenly over the vegetables and sausage.

The freshly shredded cheese will melt more smoothly and create a better texture than pre-shredded varieties.

Step 4: Prepare and Pour the Egg Mixture

• 6 eggs
• 1 cup milk
• 1/4 teaspoon garlic powder
• salt
• pepper

In a medium bowl, whisk together the eggs, milk, garlic powder, and a pinch each of salt and pepper until well combined and slightly frothy.

Pour this mixture evenly over the cheese and vegetables in the baking dish, making sure the liquid flows into all the corners and gaps.

This custard-like mixture will set up during baking and bind all the flavors together into a cohesive dish.

Step 5: Bake and Finish with Asparagus Tips

• reserved asparagus tips from Step 1

Place the baking dish in the preheated 350°F oven and bake for 15 minutes.

Carefully remove the dish from the oven and arrange the reserved asparagus tips on top in a decorative pattern, then return to the oven and bake for another 5-10 minutes until the egg mixture is set but still slightly jiggly in the very center (it will continue to cook slightly as it cools).

The frittata is done when a knife inserted near the center comes out mostly clean.

Let it rest for 5 minutes before serving—this helps the eggs set completely and makes it easier to slice.
