We are big weekend brunch eaters in my household. We used to go out, but over time (and with dietary needs in mind), I’ve come to love hosting brunch at home. It’s more relaxed, more affordable and honestly, so much easier on the schedule — all bonuses in my book.

Since we’re all fans of eggs and bacon, this keto overnight breakfast casserole has become one of my go-to recipes. It’s especially perfect for holidays like Easter or anytime you’re hosting guests and want something simple but satisfying.

Editor’s note: This recipe was originally published in 2022 and has been updated for spring brunch season.

An Easy Make-Ahead Breakfast Idea

What I love most about this recipe is how simple it is to prepare ahead of time. I prep everything the night before, cover the dish, and let it chill in the refrigerator overnight.

In the morning, while I’m making my coffee, I preheat the oven and pop it in. By the time I’m pouring my second cup, breakfast is ready.

This is one of my favorite tricks for hosting brunch — it keeps the morning stress-free and lets you actually enjoy your time with guests.

Keto Overnight Breakfast Casserole

Yields: 6 servings
Prep: 10 minutes| Cook Time: 18 minutes | Total Time: 28 minutes

Ingredients:

• 1 12 oz bag steamable frozen broccoli florets
• 1 cup shredded mild cheddar cheese
• 6 slices bacon
• 4 large eggs
• ⅓ cup milk
• ½ teaspoon onion powder
• ½ teaspoon garlic powder
• ¼ teaspoon pink salt
• ¼ teaspoon pepper

Directions:

1. If making the day of, preheat the oven to 350 degrees F. 
2. Spray an 8×8” casserole dish with cooking spray and set aside.
3. Place frozen broccoli in the microwave and steam according to package directions. Transfer steamed broccoli to a paper towel lined plate to soak up excess moisture. Use a sharp knife to chop any larger pieces into bite-sized pieces. Set aside.
4. Cook bacon in a saute pan. Transfer cooked bacon to a paper-towel lined plate to soak up excess grease. Crumble bacon and set aside.
5. Add eggs, milk and spices to a glass measuring cup or bowl. Whisk to combine.
6. Place steamed broccoli in the prepared casserole dish. Pour egg mixture evenly over the top. Layer on shredded cheese and crumbled bacon.
   ***If making this the night before, stop here and place in the refrigerator. Continue the next steps in the morning. 
7. Place the casserole in the preheated oven to bake for 18-23 minutes or until the egg is set and the top is a light golden brown.
8. Remove from the oven and cool for 5-10 minutes before serving.

Notes: Swap out the bacon for sausage or turkey sausage, or substitute the broccolli with spinach.
