Ingredients for Sausage and Egg Breakfast Casserole (Keto)

Here’s everything you’ll need to make this beauty—and trust me, every ingredient pulls its weight! I’m picky about measurements, so follow these exactly for the best results:

• 1 pound ground sausage (I use mild, but spicy works great if you like heat)
• 8 large eggs (room temp blends smoother, but cold works in a pinch)
• 1/2 cup heavy cream (measured in a liquid measuring cup—don’t eyeball this!)
• 1 cup shredded cheddar cheese (buy block cheese and shred it yourself—it melts better)
• 1/2 teaspoon salt (I use kosher for even distribution)
• 1/4 teaspoon black pepper (freshly cracked is ideal)
• 1/4 teaspoon garlic powder (the secret flavor booster!)

That’s it! Simple, right? Now let’s get cooking.

How to Make Sausage and Egg Breakfast Casserole (Keto)

Alright, let’s dive into the fun part—making this dreamy casserole! I’ve made this dozens of times, and here’s exactly how I do it for perfect results every single time:

First things first: Crank that oven to 350°F (175°C). Trust me, you want it hot and ready when your casserole is prepped—no waiting around!

Now, grab a skillet and cook your sausage over medium heat. Break it up with a wooden spoon (my grandma’s trick) until it’s nicely browned—about 5-6 minutes. Here’s the important part: drain that excess fat! I tilt the skillet and use a spoon to scoop it out, leaving just enough to keep things flavorful without making the casserole greasy.

While the sausage cools slightly, whisk together your eggs, heavy cream, salt, pepper, and garlic powder in a big bowl. Go at it for a good 30 seconds—you want everything fully blended with no streaks of egg white. I like to lift the whisk to check for smooth, uniform color.

Time to assemble! Spread the cooked sausage evenly in a greased 9×13 baking dish (more on greasing in the tips below). Pour that gorgeous egg mixture right over the top, then sprinkle your shredded cheese like you’re decorating a cake. The cheese will melt into golden perfection—I always sneak an extra pinch on top because, well, why not?

Bake for 25-30 minutes. Here’s how to know it’s done: the edges will puff slightly and turn golden, and the center should jiggle just a tiny bit when you shake the pan. It’ll firm up as it cools! Let it rest for 5 minutes before slicing—this keeps it from falling apart when you serve it.

Tips for Perfect Sausage and Egg Breakfast Casserole (Keto)

Through trial and (many) errors, I’ve learned these game-changing tricks:

• Grease your dish well—I use butter or nonstick spray in every nook to prevent sticking disasters.
• Don’t overbake! Pull it out when the center is slightly wobbly—carryover cooking finishes the job.
• Resting is non-negotiable. Those 5 minutes let the eggs set for clean slices.

Ingredient Substitutions for Sausage and Egg Breakfast Casserole (Keto)

Life happens, and sometimes you need to swap ingredients—I get it! Here are my tried-and-true keto-friendly substitutions that keep this casserole just as delicious:

• Sausage swap: Use turkey sausage (same 1:1 ratio) or even crumbled bacon (about 8 slices). For vegetarians, seasoned mushrooms work—sauté them first to remove moisture.
• Dairy-free? Swap heavy cream with unsweetened almond milk (same 1/2 cup) and use dairy-free cheddar-style shreds. The texture stays creamy!
• Cheese variations: Pepper jack adds spice, or try gruyère for richness. Just keep it to 1 cup total.
• Egg concerns: For fewer yolks, use 12 egg whites—but the texture will be slightly less rich.

See? Adaptable as your morning mood!

Serving Suggestions for Sausage and Egg Breakfast Casserole (Keto)

This casserole shines all on its own, but here’s how I love to jazz it up: top slices with creamy avocado (hello, healthy fats!), a side of crispy keto toast, or a drizzle of hot sauce for a kick. For brunch, pair it with a simple arugula salad—the peppery greens balance the richness perfectly. My kids? They go wild when I add a dollop of sour cream and extra cheese. Honestly, it’s so versatile, you can’t go wrong!

Storage and Reheating Instructions

Here’s the best way to keep your casserole tasting fresh—because let’s be honest, leftovers are half the magic! Store slices in an airtight container in the fridge for up to 3 days. When reheating, I prefer the oven (300°F for 10 minutes) to keep that perfect texture, but the microwave works in a pinch—just cover with a damp paper towel to avoid drying out. Pro tip: If it looks a tad soggy after refrigeration, pop it under the broiler for a minute to crisp up the top!

Nutritional Information for Sausage and Egg Breakfast Casserole (Keto)

Okay, let’s talk numbers—because macros matter when you’re keto! These values are estimates (ingredient brands can vary), but here’s the breakdown per generous slice:

• Calories: 320
• Fat: 26g (10g saturated)
• Protein: 18g
• Carbs: 2g (0g fiber)

See why I call this breakfast magic? Nearly 80% of calories come from fat—exactly what you want for keto fuel. The protein keeps you satisfied till lunch, and those minimal carbs? Pure victory!

Frequently Asked Questions

Q1. Can I freeze this casserole?
Absolutely! Freeze individual slices wrapped in parchment paper, then store in a zip-top bag for up to 2 months. Reheat straight from frozen—just add 5 extra minutes in the oven. The texture stays surprisingly fluffy!

Q2. Is this casserole dairy-free?
Not as written, but it’s an easy fix! Swap heavy cream for unsweetened almond milk and use dairy-free cheese. I’ve tested this with coconut milk too—just reduce it by 1 tbsp since it’s thinner.

Q3. Why did my casserole turn out watery?
Ah, the dreaded sogginess! Usually means the sausage wasn’t drained well or veggies released too much moisture. Next time, pat sausage dry with paper towels after cooking—it makes all the difference.

Can I Add Vegetables?

Yes! Spinach (squeeze out excess water) or diced bell peppers (sauté first) work best. Keep it to 1/2 cup total—too many veggies can make the eggs watery.

How Long Does It Last in the Fridge?

3 days max in an airtight container. If it smells eggy or develops a slimy film, toss it—fresh eggs shouldn’t linger!

Can I Use Bacon Instead of Sausage?

Totally! Use 8-10 cooked, crumbled bacon strips. Skip draining fat (hello, flavor!) but blot excess with a paper towel before layering.
