Why I Love This Easy Overnight Breakfast Casserole

During the week, I keep it light with Overnight Steel Cut Oats or a Greek Yogurt Smoothie.

Weekends, however, leave me craving something heartier and more indulgent.

When I’m not in the mood for something sweet (like French Toast Sticks), nothing sounds more comforting and satisfying than a heaping serving of an overnight breakfast bake with bacon, gooey fontina cheese, and TONS of vegetables.

The best part? You won’t have to wait on this easy crockpot breakfast casserole.

The prep happens the night before, so in the morning, it’s ready the moment you are!

What is a Crockpot Egg Casserole?

  • A crockpot egg casserole is just like any other breakfast casserole you would make in the oven, but it’s cooked low and slow in the crockpot instead. It also requires less hands-on tending than baked egg casserole recipes.
  • For an overnight crockpot breakfast casserole, you can prep everything the night before, and a healthy crockpot breakfast will be waiting for you when you wake up.

How to Make Crockpot Breakfast Casserole

This slow cooker breakfast casserole recipe is a savory, Mediterranean version of overnight French toast (like my favorite Overnight Blueberry French Toast) with gooey cheese, bacon, and vegetables in lieu of sweet or fruity ingredients.


The Ingredients

  • Eggs. What can you do with an extra dozen eggs? Make an overnight crockpot breakfast casserole, of course!
  • Cheese. Use one “melty” cheese and one “crumbly” cheese for a nice variety of textures and flavors. I opted for fontina for the melty cheese and feta for the crumbly.

Substitution Tip

Other tasty cheese options include cheddar, Swiss, or mozzarella (for melty cheeses) and goat cheese for a tangy crumbly cheese alternative.

  • Mediterranean Vegetables. Canned artichokes, spinach (frozen chopped spinach keeps it quick and easy), and sweet red bell pepper give this slow cooker breakfast scramble Mediterranean flair.

Market Swap

Feel free to swap other seasonal veggies into this easy overnight crockpot breakfast bake to suit your personal taste preferences.

  • Zucchini and sliced mushrooms would add a little taste of Italy.
  • Prefer kale or Swiss chard to spinach? Feel free to change it up (just sauté it first, if using raw).
  • Jalapeños, poblanos, and diced Oven Roasted Potatoes would transform this into a Southwest-style breakfast casserole.
  • Bacon. Guaranteed to make any day feel like the weekend. While egg casserole with bacon is my favorite, you can swap browned sausage or cubed cooked ham if you like.

Substitution Tip!

Don’t be afraid to experiment and try this slow cooker breakfast casserole with sausage, turkey bacon, or chorizo. Slow cooker breakfast casserole with ham is another variation readers have made with tasty success.

  • Bread. A baguette or artisan sourdough loaf is my favorite. If you use a whole-grain option, make sure the taste of the wheat isn’t too pronounced or it will overtake the more delicate flavors of the vegetables and cheeses.

Ingredient Note

I took the crockpot egg casserole no hash browns approach for this particular recipe because I personally love the fluffy, custardy, decadent texture you get with bread. If you’re looking for a breakfast casserole with potatoes, try this Healthy Breakfast Casserole or Hash Brown Casserole.

  • Dijon Mustard + Cayenne. A little of each adds depth and gives the egg casserole a true “I could be eating this in a restaurant” effect.

Recipe Adaptations

  • To Make Gluten Free. Swap gluten-free bread for regular bread (or try this Whole30 Breakfast Casserole).
  • To Make Vegetarian. For a vegetarian egg casserole, omit the bacon, and sauté the vegetables in olive oil instead. This crockpot egg casserole with bread will be plenty hearty without the meat. (You can also try this delicious Vegetarian Breakfast Casserole.)

The Directions

  1. Line your slow cooker with a disposable liner.
  1. Cook the bacon until crisp.
  1. Sauté the red pepper and shallot until softened.
  1. In a bowl, whisk together the eggs, milk, mustard, and spices.
  1. Layer the bread, vegetables, and cheese in the slow cooker.
  1. Pour the egg mixture over the ingredients and sprinkle with bacon.
  2. Cook the crock pot breakfast casserole for 7 to 8 hours on LOW. Slice and serve. ENJOY!

How do You Know When an Egg Casserole is Done?

  • When your egg casserole is done, it should be visibly golden around the edges, and the eggs should look firm and set.
  • The most foolproof method for knowing if an egg casserole is done is by checking the internal temperature with an instant-read thermometer or by inserting a knife in the center and seeing if it comes out clean.
  • What temperature should an egg casserole be cooked to? An egg casserole should be cooked to 160 degrees F.

Tips For The BEST Crockpot Breakfast Casserole

  • Easy Cleanup. I recommend using a slow cooker liner to ensure the eggs don’t stick to your slow cooker. Added benefit: you can pick up the liner by its sides and lift the whole casserole directly onto a serving plate or a casserole dish if you’d like to keep it warm in the oven.
  • Toast the Bread. If you have day-old bread, use that. If you don’t, simply toast the bread cubes in the oven for a few minutes to dry them out. This ensures the bread is primed for soaking up the yummy egg mixture.
  • Cook on LOW. If you try to cook the casserole on high, the outside edges of the eggs will burn, the insides won’t cook all the way through, and you may be forced to abandon ship and stand in line for brunch elsewhere.
  • Check Early. Mine finished at right about 7 hours. Check early to be safe—if you want to sleep longer, you can always wake up and take a peek at the casserole, pull it out if it’s done (or reset the timer if it’s not), then roll back into bed until you are ready to eat. Once you have the cooking time down for your particular crockpot model, you’ll be able to time it perfectly going forward.

Storage Tips

  • To Store. Store egg casserole in an airtight storage container in the refrigerator for up to 3 days.
  • To Reheat. Reheat casserole in a casserole or similar baking dish in the oven at 350 degrees F until hot. You can also gently rewarm leftovers in the microwave on a microwave-safe plate until warmed through.
  • To Freeze. You can freeze an egg casserole! Place leftover casserole in an airtight, freezer-safe storage container in the freezer for up to 2 months. You can also wrap individual portions and freeze them so that you can thaw one portion at a time. Let thaw overnight in the refrigerator before reheating.

Meal Prep Tip

If the casserole finishes before you are ready to serve it, you can rewarm individual servings in the microwave or place the whole thing in a baking dish, cover it with foil, and warm it in the oven.
