These 21 Day Fix Mason Jar Egg Casseroles are a perfectly portioned and portable make ahead breakfast for the 21 Day Fix!


  • 6 extra large eggs
  • 1/3 cup of unsweetened original almond milk or milk of your choice
  • 2 cups of cauliflower rice
  • 1 cup of diced bell peppers or veggies of your choice
  • 6 slices of turkey bacon, crumbled, or 6 links of diced poultry breakfast sausage
  • 2/3 cups of shredded cheddar cheese or cheese of your choice (you can double this amount and just count it as a full blue)
  • salt


  1. Preheat oven to 375 degrees and spray four, 12 oz or larger mason jars liberally with cooking oil spray.
  2. Add ½ cup of cauliflower rice to each jar and sprinkle with salt. Next, add in veggies and breakfast meat.
  3. Scramble eggs and whisk in milk. Divide egg mixture evenly among the 4 jars. Again, sprinkle with a little salt.
  4. Top evenly with shredded cheese and bake on a baking sheet uncovered for 25-30 minutes or until egg is set and the cheese begins to brown.
  5. Cool completely, then cover and store in the fridge for 3-4 days. To warm, remove cover and heat in the microwave for 1 minute.
