👨🍳 How To Make
To make this carnivore casserole, just follow these easy steps:
Step 1
Start by preheating your oven to 350F / 175C.
Heat a large skillet over medium-high meat. Add the sausage and cook the meat until it’s fully cooked. Don’t overcook. Use a wooden spoon to break the meat apart while cooking.
Step 2
Spread the sausage over the bottom of the dish (I used a 9×13-inch casserole dish).
Step 3
Take a large bowl and whisk the eggs, heavy whipping cream, hot sauce, and shredded cheese. Evenly pour the mixture over the sausage.
Step 4
Bake for 35-40 minutes. And now, you can enjoy this amazing carnivore casserole!
💡Tips
1. Don’t Overcook The Sausage
You want the breakfast sausage cooked through, but still juicy. Overcooking can make the sausage dry and tough, which will change the texture of your casserole.
Cook it just until it’s no longer pink, breaking it up with a wooden spoon as you go. This usually takes about 5-7 minutes over medium-high heat.
The sausage will continue cooking in the oven, so it’s okay if it’s not completely browned at this stage.
If you’re using a leaner sausage, you might want to add a tablespoon of butter or beef tallow to the pan to prevent sticking and add some extra flavor.
2. Grease The Baking Dish Well
Make sure to grease your baking dish thoroughly. You can use butter, ghee, or even some of the fat rendered from cooking the sausage.
Pay special attention to the corners and sides of the dish, as these areas tend to stick the most. If you have parchment paper, you could line the bottom of the dish too.
3. Keep An Eye On The Baking Time
Start checking your casserole at the 30 minute mark. It’s done when the edges are set and lightly golden, but the center still has a slight jiggle.
Don’t worry if it seems a bit wobbly in the middle – it will continue to set as it cools. Overbaking can lead to a dry, rubbery casserole, so it’s better to err on the side of slightly underdone.
If the top is browning too quickly but the center isn’t set, you can cover it loosely with aluminum foil to prevent burning.
Variations
1. Chorizo and Manchego Casserole- Use Mexican style chorizo instead of breakfast sausage. Substitute the cheddar with manchego cheese.
2. Italian Sausage and Mozzarella Casserole- Use Italian sausage, removed from casings. Use mozzarella cheese instead of cheddar. Add crushed red pepper flakes.
3. Ham and Gruyere Casserole- Substitute the sausage with diced ham. Use Gruyere cheese instead of cheddar.
4. Bacon and Cheddar Casserole– Replace the sausage with strips of cooked, crumbled bacon. Use extra sharp cheddar cheese.

Frequently Asked Questions
How can I tell when the casserole is fully cooked?
The casserole is fully cooked when the center is set and no longer jiggly, and the edges are lightly golden brown.
The internal temperature should reach at least 160F (71C) when measured with a food thermometer.
Can I substitute another type of meat for the breakfast sausage?
Yes, you can substitute other meats for the breakfast sausage, such as ground turkey, bacon, or ham.
However, keep in mind that each type of meat will bring a different flavor profile and fat content to the casserole.
If you’re using a leaner meat like ground turkey, you might want to add an extra tablespoon of butter or oil while cooking.
