The Best Keto Egg Muffins

These healthy keto egg muffins are like mini frittatas that you can bake in a muffin tin.

I love this recipe because it’s the perfect make-ahead breakfast for busy weekday mornings.  You can meal prep a batch of these egg muffins over the weekend, wrap them up, and have a healthy breakfast ready to go all week long.

One of the great things about this recipe is that you can easily customize the ingredients to suit your tastes.  In my version, I included breakfast sausage, Cheddar cheese, spinach, and bell peppers.  But, you can change it up and add cooked bacon, ham, mushrooms, or any other cooked vegetables you like.

How to Cook Eggs in A Muffin Tin

To start, you’ll gather your ingredients. If you are starting with fresh sausage, brown the meat in a skillet over medium heat, until it’s cooked through. If you are started with already cooked protein, you can skip this step!

Next, you’ll want to pre-cook any vegetables that you want to add to these egg muffins.  I like to add sauteed spinach and bell pepper.  You can also add up to a cup of roasted veggies that you have leftover from dinner.

Then, you’ll make the egg mixture. Crack 8 into a large mixing bowl.  Add some heavy cream and your favorite shredded cheese. Then, you’ll add some salt, pepper, and a little garlic powder.

Next, add the sausage and vegetables to the egg mixture, and give everything a quick stir. After that, pour the egg mixture into the muffin tin, sprinkle with extra cheese, and bake until the eggs are set and the edges are starting to brown. That’s it!

Tips for Better Keto Egg Muffins

This recipe is really easy to make, especially if you have the right equipment.  Keto egg muffins do have a tendency to stick to the muffin tin, so here are my tips to prevent that:

  1. At the very least, use a non-stick muffin tin.
  2. Be liberal with the use of non-stick spray.
  3. Use silicone muffin liners.

Ingredients in Keto Egg Cups

This recipe has everything you love about keto breakfast — sausage, eggs, cheese, and veggies — baked in individual muffin tins like personal-size frittatas.   

I choose to include ingredients that my whole family likes to eat: breakfast sausage, Cheddar cheese, nutritious spinach, and sweet bell peppers.

Eggs on the Keto Diet

Eggs are a staple of the keto diet, and for good reason. One large egg contains less than 1 gram of carbs and about 6 grams of protein, making eggs an ideal food for a ketogenic lifestyle.

Keto Friendly Sausage

Processed meats like pork breakfast sausage are generally OK on the keto diet.  Just check the label before you buy! Make sure to read the ingredients to watch for added sugars or high-carb filler ingredients.  

In general, stay away from anything labeled “maple-flavored”, and try to choose organic options if you can.

There are some great keto-friendly brands out there. If you want my recommendation for the best breakfast sausage, try ButcherBox! Their bacon and sausage are some will be the best you’ve ever had – it’s keto-approved, nitrate-free, with no added sugar.

Best Vegetables for the Keto Diet

I love to add veggies to keto egg muffins.

If you are new to keto — or just looking to track your carb intake to stay below the often-recommended 20-30 grams of carbs per day — it’s helpful to know the carb count of your favorite vegetables. keto-friendly vegetables

Vegetables — especially “above ground” vegetables like leafy greens, broccoli, cauliflower, cabbage, onions, and celery, etc. — are a healthy part of a well-rounded keto diet.  Here are the net carb counts of some popular veggies, per 100 grams of raw vegetable.

Spinach – 1g
Celery – 1g
Zucchini – 2g
Asparagus – 2g
Mushrooms – 2g
Cucumbers – 3g
Cauliflower – 3g
Cabbage – 3g
Tomato – 3g
Green Bell Pepper – 3g
Eggplant – 3g
Olives – 3g
Broccoli – 4g
Kale – 4g

Egg Muffin Recipe Variations

You can change up the ingredients to suit your family’s tastes. Here are some other ideas for variations on keto egg muffins:

  • Instead of browned sausage, crisp bacon, or diced ham.
  • Instead of spinach, try leftover sauteed kale, steamed broccoli, or Swiss chard.
  • Instead of Cheddar cheese, try Swiss or Gouda.
  • If you don’t mind few extra carbs, and fresh diced tomatoes, onions, and bell peppers
  • Another tip: start with fully cooked meat. This is especially helpful if you’re using something like leftover ground beef or even something like a shredded rotisserie chicken.


How to Store and Reheat Egg Muffins

To meal prep these muffins, you can bake a batch and store them in the refrigerator for up to 5 days.

When you’re ready to serve, grab one of these muffins and give it a quick reheat in the microwave.  (Try 30 seconds, depending on the wattage of your microwave.)

Savory keto egg muffins with sausage, egg, cheese, and veggies.


  • 6 ounces sausage
  • 1/2 cup frozen spinach
