The Base of a Breakfast Casserole
Eggs are the main base of any breakfast casserole. High in protein and among one of the most nutritious foods on the planet eggs contain a little bit of almost every nutrient we need.
Eggs are truly one of the most versatile ingredients for breakfast and can be used to prepare breakfast tacos, egg bites, waffles, pancakes, you name it!
For the base of your breakfast casserole, crack raw eggs into a large bowl and whisk them with a liquid (dairy or non-dairy) to get fluffy and light eggs before stirring in your add-ins.
- Keto-friendly dairy options: heavy cream, half and half, whole milk, coconut milk, almond milk, hemp milk, almond milk.
- Paleo and Vegetarian non-dairy options: coconut cream, almond milk, hemp milk, soy milk.
Healthy Breakfast Casserole Add-ins
Here is where you can be as creative as you want with your breakfast casserole.
Before rushing to the grocery store, shop your pantry and fridge for any leftovers you may want to utilize first!
- Low Carb Vegetables: If you are following a keto diet opt for non-starchy veggies first like spinach, kale, zucchini, broccoli or cauliflower. Always cook these first, such as steaming them, sauteing them, or roasting them, as this will help get rid of excess water or moisture, and add flavor! This is where you can multitask for your weekly meal prep; roasting off some broccoli for your dinner? Chop up 1 cup extra and set it aside after roasting for your breakfast casserole! Adding vegetables to your breakfast casserole will add flavor and extra nutrition.
- Meat: From bacon to breakfast sausage, whatever meat you choose be sure to cook it 100% before mixing it in. If you are vegetarian feel free to substitute a meat alternative such as beyond beef, soyrizo, or tempeh; just remember to fully cook whatever you choose to cook beforehand.
- Dairy (cheese): Any kind of cheese works well in a breakfast casserole, so your choice may be dependent on what you have available or what your flavor combination is (i.e. Spanish style vs Italian inspired). Some popular cheese options: American, Swiss, Monterey jack, cottage cheese, cheddar, and feta.
- Herbs and Spices: Don't forget that you can open up your spice cabinet or pick up some fresh herbs. Dried rosemary, thyme, basil, and parsley can be easy ways to add flavor to your casserole, or opt for chopping up some fresh herbs like cilantro, dill, or chives! Other dried spices that add some flair and flavor: coriander, cumin, black pepper, curry powder, sage, and oregano.
- Creative Seasonings: There are plenty of other creative ways to change up the flavors in your breakfast casserole recipes. Purchase a can of sun dried tomatoes in oil and chop them up! Other easy add-ins could be: olives, roasted red peppers, pesto, and tapenade!
Here are some go-to flavor combinations if you want something other than broccoli and cheese outlined in the recipe below:
- Bacon & Jalapeno Cheddar: fresh jalapeno, cheddar cheese, and pre-cooked bacon.
- Mushroom, Olive, and Thyme: sauteed mushrooms, chopped olives, and fresh thyme.
- The Southwest: roasted red bell pepper, tomato, onion, garlic, queso fresco, and paprika
- Italian Breakfast Sausage: Italian breakfast sausage, oregano, and feta
You can really choose any kind of flavor combination you’d like, and this is a great opportunity to utilize any leftover ingredients or make a trip to your local farmers market to see what's in season!
