This Cheesy Broccoli Sausage Egg Casserole is an easy, make-ahead breakfast filled with sausage, broccoli, cheddar cheese, and eggs. It's a perfect low-carb, keto-friendly brunch recipe.
Ingredients and Substitutions for our Egg Casserole
- Ground pork sausage: Substitute ground chicken or turkey sausage.
- Shallot: I prefer using shallots for their mild flavor. Use yellow or white onions if that is all you have available.
- Red pepper and broccoli florets: These two vegetables work well for me. I recommend making the egg casserole following the ingredients list. Then, substitute vegetables and cheddar cheese once you are comfortable with the recipe.
- Large eggs
- Milk: You can also do half milk and half heavy cream.
- Dried parsley/dried basil: My testing of different dried herbs showed me that dried parsley and basil complement the flavors of the eggs and vegetables.
- Cheddar cheese: Use a block of cheese and shred it yourself so the cheese melts properly. Pre-shredded cheese can have a film that prevents the cheese from melting smoothly.

Make-ahead, storage, and freezer tips
Storage: Refrigerate leftovers in a covered airtight container for 2 days.
Freezer Instructions: After baking, freeze individual slices of egg casserole for later. Place the egg pieces on a baking sheet to freeze for about 30 minutes. This will keep the pieces from freezing together.
Wrap well in plastic wrap and aluminum foil, or use a food saver to freeze. Defrost overnight as needed. Reheat egg slices from the freezer, wrapped in aluminum foil. Reheat at 350°F/177°C for about 15-20 minutes.
Variations for our Egg Casserole
Want to change up the recipe?
- Protein - Use leftover maple ham or crumbled bacon in the egg casserole.
- Vegetables: Try sautéed spinach, sautéed mushrooms, asparagus, or chopped zucchini. A great recipe to use up vegetables that need to be used up.
- Use leftovers - leftover veggies.
FAQs for the best Broccoli Egg Sausage Casserole Tips
You can make sausage broccoli egg casserole one day ahead and keep it in the refrigerator until you are ready to reheat it. Reheat at 350°F for about 15 minutes.
I've made this egg casserole many times; frozen broccoli florets are the easiest to use.
If you use fresh broccoli florets, sauté them for 5-6 minutes to ensure they will be cooked through after the casserole is baked.
Or blanch the broccoli for about 3 minutes, then place them in an ice bath before adding to the egg mixture.

Sausage and Egg Casserole
Equipment
Ingredients
Instructions
- Preheat oven to 350°F/177°C. Spray a 9" x 13" casserole dish with non-stick baking spray. Set aside.
- In a large mixing bowl, whisk 10 large eggs, ⅓ cup whole milk 1 cup cheddar cheese (shredded), ½ teaspoon dried parsley, ½ teaspoon dried basil, ½ teaspoon garlic powder, ½ teaspoon black pepper, and ½ teaspoon kosher salt. Set aside.
- In a large skillet over medium heat add 1 pound ground breakfast pork sausage, breaking up sausage as it browns, and cook sausage until browned through and no longer pink, about 5 to 7 minutes.
- Use a slotted spoon to remove the cooled crumbled cooked sausage mixture and add it to the egg mixture. Drain off and discard excess grease, leaving about 1 Tablespoon of sausage drippings in the sauté pan to cook the vegetables.
- To the pan, over medium heat, add 1 medium shallot (peeled and diced), 1 large red pepper (seeded and diced), and 2 cups broccoli florets (defrosted and chopped) to soften the vegetables, about 5 minutes. Remove from heat. Let cool slightly.
- Stir the cooled vegetables into the egg and sausage mixture.
- Pour the egg mixture into the prepared casserole dish.
- Cover with aluminum foil. Bake in the preheated oven for 30 to 45 minutes. The casserole will be almost cooked through.
- Remove foil. Let bake another 5 minutes or until the casserole is cooked through. The center of the egg casserole will not be soft or jiggle.
- Remove the egg casserole from the oven and let rest for about 5 minutes. Slice and serve with additional cheddar cheese, shredded and chopped fresh parsley optional.

Can I make this ahead? If so, how long can it sit in the refrigerator?

Hi Rebecca, you can make this one day ahead and keep it covered in the fridge until ready to reheat. Reheat t 350 degrees until warmed through, around 10 minutes.

Aw thank you, enjoy
Marcia
Could I use spinach instead of broccoli?
Eileen xo
Hi Marcia, absolutely spinach can work. However, it is watery so you would want to use frozen defrosted spinach that is squeezed out. You do not want it releasing liquids into the eggs. If using fresh spinach,
sauté it and again squeeze out excess liquid before adding it to the eggs. If you have any other questions, please let me know. I hope you enjoy the eggs.
