Recipe variations

  • Vegetable substitutions – This recipe is quite flexible, you can add or remove vegetables as desired. If you don’t care for sweet potatoes, you can omit them. 
  • Milk substitutions – You can use any type of milk preferred in this recipe, dairy or non-dairy! If you’re eating low-carb, especially Keto, choose milk that doesn’t have any carbs, like almond milk.

Cooking bacon

If you don’t have space in your oven for 2 baking sheets, or if you only have 1 baking sheet, you can cook the bacon in a skillet. Bacon will cook quicker and more even if you chop it into small pieces before cooking. We love using kitchen scissors to cut bacon, super quick and minimal mess!

Storage and Reheating Guidelines

  • Make-ahead: To make ahead, assemble the casserole all the way up until the final baking step, cover it with plastic wrap, and place it in the refrigerator until you’re ready to bake (up to 1 day).

Ingredients That Make a Difference

Each ingredient in our low-carb breakfast casserole plays a unique role in crafting its delectable flavor profile while contributing to a diabetes-conscious diet. Here’s a quick overview of key components and why they’re beneficial:

  • Eggs: Packed with high-quality protein and essential nutrients, eggs are a nutritional powerhouse. They provide a steady release of energy and help maintain satiety, keeping your hunger at bay.
  • Protein: Whether it’s sausage, ham, or tofu, the inclusion of protein sources ensures you’re getting a satisfying meal. Protein also aids in muscle maintenance and repair.
  • Colorful Vegetables: Bell peppers, sweet potatoes, and onions introduce an array of vitamins, minerals, and antioxidants. These veggies add vibrant colors, enticing flavors, and a boost of fiber, which helps regulate blood sugar levels.
  • Cheese: Cheese contributes a dose of protein and healthy fats, enhancing both flavor and texture.
  • Herbs and Spices: Flavorful herbs like chives, thyme, and a pinch of cayenne pepper elevate the taste without adding extra calories or carbohydrates. Plus, certain herbs may have potential health benefits, such as anti-inflammatory properties.

Crafting Your Low-Carb Breakfast Casserole

Preparing our low-carb breakfast casserole is a breeze, and a few extra tips can ensure your dish turns out perfect every time:

  • Sauté Vegetables First: Before layering the ingredients, sauté the colorful vegetables lightly. This not only enhances their flavors but also removes excess moisture, preventing a watery casserole.
  • Protein Distribution: Evenly distribute your chosen protein source across the casserole. This ensures that every slice contains a balanced combination of flavors and nutrients.
  • Herb Infusion: When adding herbs and spices, consider mixing them into the beaten eggs or sprinkling them between layers. This allows the flavors to permeate the entire casserole.
  • Careful Cheese Placement: While cheese adds a delightful touch, it can also create a crispy layer if placed on top. If you prefer a more uniform cheesy distribution, mix shredded cheese into the egg mixture.

Variations and Serving Suggestions

While our Low-Carb Breakfast Casserole is already a delicious and nutritious option, don’t hesitate to get creative and tailor it to your preferences:

  • Veggie Delight: If you’re a vegetarian or simply looking to increase your vegetable intake, skip the meat and load up on various veggies. Consider adding mushrooms, zucchini, spinach, or even a handful of kale for an extra nutrient boost.
  • Spice it Up: For those who enjoy a bit of heat, incorporate diced jalapeños or a dash of hot sauce into the egg mixture. The slight kick of spiciness can provide an invigorating morning experience.
  • Cheese Fusion: Experiment with different cheese varieties to diversify the flavor profile. Try a blend of cheddar and mozzarella for a melty, gooey texture or a sprinkle of feta for a tangy twist.

A Diabetic-Friendly Choice

By prioritizing protein sources, fibrous vegetables, and healthy fats, this dish helps prevent drastic blood sugar fluctuations.
