Rebekah's Keto Egg Casserole Recipe

Cook Time: 35 minutes

Breakfast Casserole Recipe

Ingredients

  • 1 (8 ounce) package breakfast sausage
  • 12 eggs
  • 1 (8 ounce) package shredded Cheddar cheese
  • cup heavy whipping cream
  • 1 tablespoon minced onion
  • 2 teaspoons dry mustard
  • 1 teaspoon dried oregano
  • Salt and ground black pepper to taste

Directions

Step 1: Preheat the oven to 350F (175C).

Step 2: Heat a large skillet over medium-high heat. Add the breakfast sausage and cook, breaking it apart with a wooden spoon, until browned and crumbly, about 5 to 7 minutes.

Step 3: Spread the cooked sausage evenly over the bottom of a 9x13-inch casserole dish.

Step 4: In a separate bowl, whisk together the eggs, shredded Cheddar cheese, heavy whipping cream, minced onion, dry mustard, oregano, salt, and black pepper until well combined.

Step 5: Pour the egg mixture over the cooked sausage in the casserole dish, ensuring it is evenly distributed.

Step 6: Place the casserole in the preheated oven and bake for 30 to 40 minutes, or until the casserole is firm and cooked through.

Step 7: Once done, remove the casserole from the oven and let it cool for a few minutes before serving.

This is my first step to a Keto diet and I chose this recipe because it is a casserole I can eat all week. I need to have my food ready to stick to this. I changed a couple of things as follows: I omitted the oregano and added garlic and cayenne pepper - didn't measure but was about 1/2 teaspoon each. I added 2 cups of baby spinach. I also used a whole large yellow onion and my onion was sautéed with the sausage. After pouring the egg mixture over the sausage and onion I did stir it up to mix it all in. I'm sure the addition of the spinach made it a big chunkier than just pouring egg over it. Lastly I save about 1/2 cup of cheese to sprinkle around the top. Bon Appetit!

I used one pound sausage, one teaspoon mustard powder. and a 9 x 9 pyrex. It took 35 minutes and it was perfect, Oh and I forgot the shredded cheese so I sprinkled it on top and another 5 minutes in oven. My family loved it for Christmas breakfast, I only did 4 stars because I cannot imagine trying to stretch a half pound sausage on bottom of pan, especially a 9 x 13 as specified in recipe. Thank you.

A quick, easy keto breakfast - I halved the recipe, used pre-cooked sausage crumbles, and made it the night before. I cooked it at 350 for 26 minutes in a glass casserole and it was perfect. Reheated portions in microwave the next morning. Will definitely be a regular in our keto meal rotation.

Followed recipe. Loved it!!! The seasoning is perfect and the texture is moist but not wet, even when reheating. I cut into 8 pieces and put each piece in a baggy in the fridge. Ate with toast and some strawberries every morning. So satisfying and heats up great. I'm going to make one today with mushrooms, onion, and spinach. All sauteed of course so they don't release liquid and make eggs runny. An excellent base with worlds of possibility.

DELICIOUS!!! We're ok day 2 of this casserole, and my husband still can't stop talking about it!!! We have one more day of it, and I am almost sad to see it go. The eggs were perfect... I cut the recipe in half, but otherwise followed the egg recipe to a T. I added other veggies (more onions, mushrooms, and peppers) and did half sausage, half bacon, but the base was the same... sooooo yummy!!! Thanks for an amazing recipe!!!

very good, plus easy to change to whatever you like. I like to cook this in muffin tins then wrap individually in saran wrap this makes it quick and easy to grab for work. I make a lot because they freeze well

I made two substitutions since I didn’t have any heavy cream; or chicken sausage; I used sour cream and bacon crumbles instead. I chose to lightly sauté some spinach, green peppers and onions to add into the recipe too. All personal choices, but if I had all the ingredients on hand, I would’ve used them as written in the recipe. Thanks for sharing; we enjoyed it!

This is an amazing base recipe! We are Jewish, so did turkey sausage for the meat. I have a fresh onion allergy in my household, so I subbed 1 tsp of onion powder for the fresh onion and we wanted a little smoky flavor, so I added a heaping 1/8 tsp of chipotle powder. Folks. Even my texture-sensitive, doesn't like anything remotely spicy, pickiest eater in the house devoured it! I am SO happy to finally have a healthy, easy to fix, go-to breakfast for those busy weekday mornings!

I followed the suggestions of a couple reviewers and used a 16-oz roll of sausage, but I used turkey breakfast sausage. I don't care for a lot of mustard, so I used 1 tsp instead of 2 tsp dry mustard. I added a bit of ground red pepper and served the casserole with salsa. Yummy! So easy, and will last all week! This recipe will definitely be used a lot in my house!

I used half spicy half original flavor sausage. I did not have heavy cream on hand so melted 1/4 c butter to 2/4 c milk and mixed it together. Also omitted ground mustard because not on hand. Added a tap of cream of tartar to the eggs to make them fluffy and viola! Turned out excellent!

YUMMY and so fluffy! I mixed it for 10 to 15 min on low speed using my stand mixer. I think the heavy whipping cream made it so fluffy! I served it with fruit and sour cream. I will definitely make this often. It was so easy! :-D

I made this last night for the family, although I'm the only one doing keto. It didn't matter. Everyone loved it. I did add some diced peppers, but otherwise the recipe is perfect. Thanks for sharing it.

This is an awesome breakfast casserole. I made it and cut it into servings for my breakfast thru the week. Heats up well in the microwave. The only change I made was to add a hand full of baby spinach. Will absolutely make it again.

I added mushrooms and a bit of diced green pepper, otherwise I followed the recipe exactly. I may have overdone it a bit on the “salt to taste.” Next time I will skip the salt entirely and let people make their own choices.
