Sunday Morning Sausage and Mushroom Frittata – this is perfect for serving Sunday brunch to a crowd or for making ahead for meal prep!

This is Sunday morning at our house (okay – this or vanilla cake donuts with chocolate frosting …. it is all about balance ? ). It comes together so easily, tastes amazing and makes delicious leftovers. it is a win-win and you need to make it this weekend for sure!
Our weeks are so incredibly busy, so I cherish every weekend morning to their fullest. They are full of snuggles with my girls, making breakfast, watching cartoons, walks to the park, reading books…. and making frittata. I love creating recipes for the blog, but I also LOVE sharing recipes with you guys that our family has been eating forever. They are just more personal and carry so many more stories and memories with them. This is one of them. It reminds me of perfectly normal weekend mornings, Mother’s Day brunch, weekends with friends… this recipe is always a hit and so often has been at the center of a group of people I love.
The leftovers aren’t bad either.
If you buy the right sausage (no sugar added), this will Whole30 compliant too – I like to eat it with a side of mango kombucha ?
Speaking of crazy weeks, this one has been insane so I am keeping it short and sweet tonight! I hope you guys have an awesome weekend – I have an incredibly long list of recipes I want to try this weekend, so I will be busy in the kitchen!




If you aren’t feeling may mango kombucha suggestion, maybe serve it with some cold brew? Might I suggest this Honey Lavender Cold Brew Latte??? So good ? Happy weekend you guys!

Ingredients
- 1 tablespoon avocado oil
- ¼ cup sweet yellow onion, diced
- 1 teaspoon garlic, chopped
- 1 pound ground sausage
- 3 handfuls fresh spinach
- 2 cups mushrooms, sliced
- 12 eggs, beaten
- 1 tomato, sliced
Instructions
- Sauté: Take a large, 12 inch cast iron skillet and place on stovetop, on high heat. When your pan is hot, add 1 tablespoon avocado oil and coat the pan. Add diced onion and 1 teaspoon garlic and let reduce, stirring constantly for about 2-3 minutes.
- Brown Sausage: Add 1 pound ground sausage and break apart to fully brown. Reduce heat to medium heat.
- Add Veggies: Add 3 handfuls fresh spinach and stir, letting it wilt. Then add 2 cups mushrooms and move around to cook down a bit.
- Add Eggs: Pour the whisked eggs on top. Use a rubber spatula to gently fold the ingredients together. If the eggs don't quite cover all of the sausage and mushrooms, you can quickly whisk 2-3 more eggs together and pour on top. Let cook without stirring for about 10-15 minutes, or until the eggs around the outside edge start to firm and only to top is uncooked.
- Tomato + Broil: Place tomato slices in a single layer on top and transfer to oven. Broil in the oven for 4-6 inches from the top for about 2 minutes, or until the top starts to brown and the eggs are fully cooked.
- Serve: Remove from the oven to let cool slightly and then serve.
