Everyone will gather and dig into this cheesy breakfast casserole without hesitation. The savory mix of eggs, cheese, and greens is an instant crowd-pleaser. It’s quick to prep and delicious to eat!
Simple Morning Meal Prep
Breakfast casseroles are an all-in-one dish you can make for weekly meal prep or when company comes over.
It’s simple enough for daily eating but also serves a crowd nicely. The current recipe contains 6 servings when cooked in an 8×8-inch baking dish.
If you need more portions, all you have to do is double the recipe and bake in a 9×13-inch baking dish. Viola!
Breakfast casseroles are one of my favorite keto breakfast recipes. With eggs, veggies, and cheese wrapped up in one dish, how can you go wrong?
Egg bakes are quick meal ideas that easily double for brunch or lunch. I really enjoy the cold leftovers.
Keto omelettes take it to the next level of quick meal prep, but usually, only make one serving at a time. Lucky for you, I have suggestions for all of these meals, so you can pick and choose whatever you enjoy most.
How to Make a Low-Carb Breakfast Casserole Recipe
Gather 10 ingredients and you’re halfway to making a vegetarian breakfast casserole. Prep it all in just 10 minutes.
Mushrooms – This might surprise you, but I find that mushrooms are very filling. It’s nice to start the day with a satiating meal and gives me energy all day long.
Onion and garlic – A classic combination of flavorful add-ins.
Butter – Choose grass-fed butter, if you can
Spinach – Wilt the leaves a little by cooking in the skillet before combining with the eggs. Substitute with any of your favorite leafy greens: Swiss chard, kale, arugula, etc.
Eggs – Opt for free-range, pastured eggs or raise them yourself!
Cheese – I like combining cheese like ricotta or goat cheese with something like cheddar or mozzarella. Pairing a non-melting cheese with a type that melts is a guaranteed win!
Salt and pepper – Just a pinch of seasoning here!
- Preheat the oven to 350°F (177°C).
- Sauté mushrooms, onion, and garlic in the butter in a skillet or frying pan over medium heat for 2 minutes.
- Add the spinach to the pan and frequently stir for about 5 minutes while the leaves wilt.
- Add cheese to the whisked eggs in a bowl. Season with salt and pepper.
- Add the sauté to the eggs. Mix well and pour into a greased 8×8-inch baking dish.
- Bake for 20 to 25 minutes, until top turns golden brown and the center sets.
- Remove from heat and serve warm or at room temperature.
Cold leftovers are great too!
I pack leftovers with a can of wild-caught fish and avocado for lunch. It’s delicious!
