Moreover, this recipe is remarkably simple to create. You can conveniently bake it in advance and reheat it later, as the leftovers retain their deliciousness.

I absolutely adore this delightful casserole that has swiftly claimed its spot as one of my beloved breakfast choices when I host brunch gatherings with friends.

Its indulgent flavors and effortless preparation make it a true winner. What’s even better is that I can prepare it ahead of time and simply reheat it, adding to its appeal.

While numerous casseroles may excel in taste but lack visual appeal, this one is a true stunner, which is an added bonus. The cheese topping turns a luscious golden hue as it bakes, and the vibrant spinach contributes a beautiful burst of color.

Ingredients

You will only require a handful of simple ingredients to create this delicious and satisfying keto breakfast casserole. The recipe card below contains the precise measurements.

Let’s delve into the details of what you will need:

  1. Eggs: For this recipe, I recommend using large eggs. They are a versatile ingredient and work well in most of my recipes, including this one.
  2. Heavy cream: Adding heavy cream to the egg mixture will elevate the creaminess and richness of the casserole. It’s a wonderful addition that enhances the overall texture.
  3. Seasonings: To enhance the flavor profile, we will incorporate a combination of seasonings. I recommend using Kosher salt, black pepper, garlic powder, and a dash of red pepper flakes. These spices will provide a savory and mildly spicy kick to the casserole.
  4. Shredded cheese: In this recipe, I prefer using sharp cheddar cheese. However, feel free to experiment with different types of melty cheese. Provolone and gruyere are excellent options that complement the dish exceptionally well. The choice of cheese can add distinct flavors and gooey goodness to the casserole.
  5. Fresh pork sausage: I personally purchase my fresh pork sausage from Whole Foods, but you can also prepare your own by mixing fresh ground pork with your favorite spices. Using high-quality sausage ensures a burst of savory flavor in every bite.
  6. Fresh spinach: For this recipe, we will be incorporating whole baby spinach leaves. Unlike chopping them, using the leaves in their natural form adds a delightful texture and vibrant color to the casserole. It’s a simple way to incorporate some nutritious greens into the dish.

Instructions

Making this keto breakfast casserole is a breeze! Simply scroll down to the recipe card for comprehensive instructions. Here’s an overview of the basic steps:

  1. Whisk together eggs, heavy cream, shredded cheese, and seasonings.
  2. In a large skillet, cook the sausage, ensuring you break it up into small chunks as it cooks.
  3. Once the sausage is cooked, turn off the heat and gently stir in baby spinach leaves. The residual heat in the pan will cause the spinach to slightly wilt.

The subsequent action involves placing the sausage mixture in the base of a baking dish and pouring the eggs over it.

Afterward, generously sprinkle the casserole’s surface with additional cheese and proceed to bake it in a 400°F oven for approximately 25 minutes. And there you have it! A simple, satisfying, and mouthwatering dish.

Expert Tips

You have the option to substitute fresh garlic for garlic powder.

The red pepper provides a subtle spiciness. Personally, I don’t find it overwhelming. However, if you’re not fond of spicy dishes, simply add a pinch or omit it entirely.

If you prefer to use frozen spinach leaves, it’s important to defrost them beforehand and ensure thorough drainage. This step is crucial to prevent the casserole from becoming watery.

Variations for The Recipe

I love this recipe as is and almost always make it as written. But in case you’d like to vary the basic recipe, here are a few ideas for you:

  • You can use any type of sausage that you enjoy. Breakfast sausage will obviously have the traditional flavors that we associate with breakfast meat. But there’s no reason not to use, say, Italian sausage or spicy sausage.
  • If you don’t eat pork, you can use ground chicken or ground beef instead of ground pork.
  • You can replace the heavy cream with softened cream cheese or with whole-milk Greek yogurt.
  • Use any cheese you like as long as it’s relatively melty. Gruyere is fabulous in this casserole, and I also like Monterey Jack cheese.

Storage Suggestions

The leftovers can be stored in a sealed container in the fridge and will remain fresh for 3-4 days. For optimal enjoyment, gently reheat them in the microwave at 50% power. Now, here’s a little secret—I occasionally indulge myself by cutting a piece and savoring it cold, right from the fridge!

To ensure I have delicious leftovers throughout the week, I sometimes prepare two casseroles. This way, I don’t have to worry about making breakfast egg muffins on those weeks when I indulge in this delightful casserole.

Description

This keto breakfast casserole is a complete meal. It's made with sausage, eggs, cheese, and fresh spinach. It's so delicious and - just as important - it's very filling!

Recipe Ingredients

Instructions

  1. Preheat your oven to 400°F. Lightly grease a square 9-inch pan.

  2. In a large bowl, whisk the eggs with the heavy cream, salt, pepper, garlic powder, and red pepper flakes. Use a rubber spatula to mix in ½ cup of the shredded cheddar. Set aside.

  3. Heat a large 12-inch nonstick skillet over medium-high heat. There’s no need to add oil. Add the sausage and cook, stirring and breaking it up, until browned, 5-7 minutes.

  4. Turn the heat off and mix in the spinach leaves (you can leave them whole), just until they are very slightly wilted from the pan’s residual heat.

  5. Transfer the sausage-spinach mixture to the prepared baking dish, spreading it evenly on the bottom.

  6. Give the eggs another mix, and then pour them into the pan on top of the sausage mixture. If needed, you can gently stir the mixture inside the pan to more evenly spread out the sausage and spinach.

  7. Sprinkle the remaining ½ cup of cheese on top.

  8. Bake the casserole until the eggs are set and the cheese is golden brown. In my oven, this takes 25 minutes. Your first clue that it’s ready will be the AMAZING smell that will fill your kitchen!

  9. Allow the casserole to rest for 10 minutes before cutting it into nine squares and serving.

Note

I portion the casserole into nine squares, making each serving equivalent to one square, which constitutes 1/9 of the casserole.

Fresh garlic can be substituted for powdered garlic.

A touch of red pepper lends a subtle spiciness without being overpowering. However, if you prefer milder flavors, simply add a pinch or omit it entirely.

When using frozen spinach leaves, ensure they are fully defrosted and thoroughly drained to prevent any excess water from making the casserole soggy.

Frequently Asked Questions

Expand All:
How many carbs are in a keto breakfast casserole?

This cheesy sausage and egg breakfast casserole is super easy to make and great for meal prep and holiday breakfasts. With only 1g net carb per serving, it's keto-friendly, low carb, and gluten free.

Can you eat a cooked breakfast on keto?

Traditionally, a big cooked breakfast includes toast, eggs, bacon, mushrooms, sausages, and often, baked beans. The toast, bead, and beans are not keto but it is so easy to adapt or omit items to turn it into a big keto fry up.

What ingredients are in a breakfast casserole?

The classic ingredients are those that most of us consider as breakfast foods, so definitely eggs, often milk (or heavy cream in our case), breakfast meat such as sausage, cheese, and - for non-keto casseroles - usually bread. I like to add a veggie too, and spinach is perfect.

What is the best sausage for breakfast?

Any sausage labeled as "breakfast sausage" would be a classic choice, since it's seasoned in a way that we have come to associate with breakfast foods.

However, there's nothing wrong with using any type of sausage you like, enjoy, and have on hand. For example, Italian sausage is very good in this casserole.
