The Addictive Low-Carb High Protein Breakfast Casserole (15-Minute Prep!)
Afraid of dry, rubbery morning eggs? This low-carb high protein breakfast casserole is your foolproof solution. We blend cottage cheese into the base, creating a shatteringly crisp edge with a velvety, melt-in-your-mouth center. A deeply satisfying, effortless start to your day.
The Magic Behind the Bake
- The Secret to Soufflé Fluffiness: Blending cottage cheese directly into the eggs creates a luxurious, airy texture without relying on heavy cream.
- Bold, Farmhouse Flavors: A dash of smoked paprika gives this smoky veggie breakfast casserole a deep, savory richness that perfectly complements the earthy mushrooms.
- Weekend Taste, Weekday Speed: Just a quick vegetable sauté and a rapid blender spin, and the oven does the rest of the heavy lifting.
A Nourishing Morning Foundation
This bake fits beautifully into a low-carb routine. It relies on wholesome, flavor-packed ingredients that bring incredible satisfaction to the breakfast table.
For a complete weekend spread, it is wonderful alongside a Savory Ham and Broccoli Breakfast Bake if you have a larger family gathering. If the kids are craving something sweeter, I love whipping up some High-Protein Cottage Cheese Pancakes just for them!
The Simple Assembly
Building this gorgeous centerpiece is incredibly straightforward. First, you will sear the fresh mushrooms to coax out their deep, savory notes and evaporate any extra moisture.
Next, toss in the colorful peppers and onions until perfectly softened, folding in the baby kale just until it delicately wilts.
The real transformation happens in the blender: whirl the eggs, cottage cheese, and milk until completely smooth. Pour that creamy liquid gold over your veggie base, top with cheese, and bake until beautifully puffed!
Kitchen Secrets & Variations
- Avoid Watery Eggs: Always let the mushrooms brown undisturbed first. Cooking off that natural moisture guarantees a firm, sliceable texture.
- Cheese Swaps: Want a sharper, tangier bite? Swap the mild Colby-Jack for a robust sharp Cheddar or even a crumbly feta.
- Storage Magic: Keep leftovers tightly sealed in the fridge for up to 3 days. A quick microwave zap brings back that fresh-out-of-the-oven aroma instantly.
- Don’t worry if some of your vegetables float to the top or sink to the bottom—it creates a beautifully rustic, inviting farmhouse look!
Frequently Asked Questions
Can I prepare the ingredients ahead of time?
Absolutely! You can chop all the fresh vegetables the night before. Having everything prepped makes your morning assembly lightning fast.
Do I absolutely have to use a blender?
While whisking by hand works in a pinch, the blender is the ultimate secret to getting that cottage cheese completely smooth so it melts right into the eggs.

Description
This adapted high-protein casserole brings a smoky American farmhouse twist to the classic veggie breakfast bake.

Packed with colorful vegetables and a hint of smoked paprika, this dish is a satisfying, nutrient-dense option that helps keep you full throughout the morning.
Ingredients
Vegetable Sauté
- 2 tablespoons extra-virgin olive oil, divided
- 1 medium red bell pepper, chopped (approx. 1 ¼ cups)
- 1 small yellow onion, chopped (approx. 1 cup)
- 4 ounces fresh mushrooms (shiitake or oyster), sliced (approx. 1 cup)
- 1 package (5 ounces) baby kale
- 1 ½ teaspoons garlic powder
- ½ teaspoon smoked paprika
- ¼ teaspoon crushed red pepper flakes
- ¼ teaspoon salt, divided usage
Egg & Cheese Base
- 8 large eggs
- 1 ¼ cups shredded Colby-Jack cheese, divided
- ½ cup small-curd 2% cottage cheese
- ⅓ cup 1% low-fat milk
Instructions
- Prepare the oven and dish: Preheat your oven to 350°F (175°C). Lightly grease an 8-inch square baking dish with nonstick cooking spray and set aside.
- Sauté the mushrooms: In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add the sliced mushrooms and cook undisturbed for about 4 minutes until browned. Stir and cook for another 3 minutes to ensure excess moisture evaporates (this prevents a watery casserole).
- Cook remaining vegetables: Add the chopped bell pepper, onion, ⅛ teaspoon of the salt, and the remaining 1 tablespoon of olive oil to the skillet. Sauté for about 4 minutes, stirring frequently, until the vegetables soften.
- Wilt the greens: Stir in the baby kale, garlic powder, crushed red pepper, and smoked paprika. Cook for 1–2 minutes until the kale is wilted down. Remove from heat and let the mixture cool for 5 minutes.
- Blend the base: While the vegetables cool, combine the eggs, cottage cheese, 1% milk, ½ cup of the Colby-Jack cheese, and the remaining ⅛ teaspoon salt in a blender. Process on low speed for 20 seconds until the mixture is completely smooth and creamy.
- Assemble layers: Spread half of the cooked vegetable mixture evenly across the bottom of the prepared baking dish. Pour the egg mixture over the vegetables. Scatter the remaining vegetable mixture on top (some may sink, which is fine) and sprinkle with the remaining ¾ cup Colby-Jack cheese.
- Bake and serve: Bake for 35–40 minutes, or until the edges are puffed and golden brown, and the center is set (internal temperature should reach 165°F). Let the casserole rest for 10 minutes before slicing to allow it to firm up.
Notes
- Allergy Alert: Contains Eggs and Milk. To make this gluten-free, ensure your spices and cottage cheese are certified GF.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven.
- Variation Tip: For a sharper flavor profile without extra salt, try swapping the Colby-Jack for sharp Cheddar cheese.
