Mushroom, Bell Pepper, and Cheese Breakfast Casserole
with bacon / Bloody Mary cocktails
This brunch-friendly casserole can really be served at any time of day. If you're celebrating Christmas, the casserole can be assembled ahead and left in the refrigerator overnight, making it an easy meal to serve on a busy, celebratory morning.
Smarts: Just for fun, we're including a recipe for a Bloody Mary Cocktail. Most of the ingredients are optional (including the alcohol) because the drinks will be fine, though a bit less flavorful, if you want to skip one. Customize the drinks however you'd like and be sure to taste and adjust as you go.
- Bell peppers, red - 1, diced
- Onions, medium - 1, diced
- Cheese, Colby Jack or cheddar - 4 oz, shredded (look for pre-shredded to save time)
- Baguette - 8 oz, cubed (sub any type of bread)
- Mushrooms, any button - 8 oz, sliced (look for pre-sliced)
- Eggs - 8
- Milk - 1 cup
- Salt - 1/2 tsp
- Black pepper - 1/4 tsp
- Oil, cooking - 1 Tbsp
- Bacon - 8 strips
- Limes - 1, juice of
- Celery salt - 1/2 tsp
- Horseradish (opt) - 2 tsp (more or less to taste)
- Tomato juice - 4 cups
- Hot sauce - to taste
- Vodka (opt) - 4 Tbsp
- Celery stalks (opt) - for serving
- Olives, green (opt) - for serving
- Bell peppers / Onions / Cheese - Prep as directed. Combine bell peppers and onions in one container. Store cheese separately. (Can be done up to 5 days ahead)
- Baguette / Mushrooms - Prep as directed. Store separately. (Can be done up to 3 days ahead)
- Make Bloody Mary mix - Whisk together lime juice, celery salt, horseradish, tomato juice, and hot sauce. Taste and add more lime juice if you’d like it more tart and more horseradish or hot sauce for more spice. You can also add more celery salt if you’d like more of that celery flavor. (Can be done up to 3 days ahead)
- Eggs - Whisk eggs with milk, salt, and pepper.
- Heat oven to 350F / 177C. Spray a square baking dish with nonstick cooking spray or brush with some cooking oil.
- While oven heats, heat a large saute pan with oil over medium heat. Add mushrooms and saute until mushrooms are golden brown and very tender, ~8 minutes.
- To mushrooms, add onions and bell peppers and continue cooking until onions are soft, 3 to 4 minutes more. Season with some salt.
- To prepared baking dish add half the bread cubes, half the sauteed vegetables, and then half the cheese. Repeat those layers, ending with cheese on top.
- Pour egg mixture over casserole.
- Transfer baking dish to oven and bake, uncovered, until eggs are nearly set in the middle, 40 to 45 minutes.
- After the dish is finished baking, leave it on the stovetop for 5 minutes before you slice into it. (The eggs will continue to firm up while the casserole sits.)
- While casserole is resting (or near the end of cooking), heat a griddle or large skillet over medium heat. Add bacon and fry on both sides until crisp, ~8 minutes total. Transfer bacon to a paper towel-lined plate.
- Stir vodka (if using) into Bloody Mary mix. Divide between glasses and garnish with celery stalks and olives.
- Slice casserole and serve with bacon. Enjoy Bloody Mary cocktails on the side.
Egg bake was great. We're just not tomato juice people, so the Bloody Mary just wasn't our jam.0 Helpful
It was pretty good. I used vegan cheese and plant-based milk.0 Helpful
A lighter meal but still very good. I sometimes find egg based meals can be bland, but this one had good flavor0 Helpful
I'm pretty sure this was user error, but we did not like this at all.0 Helpful
Excellent casserole and just as good reheated. Will make this again. Update - the second time I made it I used too much bread and it was dry and chewy - so be sure you get the ratios correct.0 Helpful
Love how easy this is and I made a lot for left overs.0 Helpful
