Ground Beef
Ground beef is a fantastic protein source on the keto diet. It’s high in essential amino acids, iron, and vitamin B12, all of which are important for maintaining energy, supporting muscle growth, and keeping your immune system strong. Compared to other meats, ground beef also contains a higher percentage of healthy fats, making it an ideal choice for a keto-friendly meal.

Mushrooms are a low-carb, nutrient-dense vegetable that work wonderfully in this casserole. They’re packed with antioxidants, fiber, and various vitamins and minerals, such as vitamin D, potassium, and selenium. Plus, their earthy, savory flavor complements the beef and creamy sauce perfectly.
Heavy Cream
Heavy cream is a staple ingredient in keto cooking, as it’s high in healthy fats and low in carbs. It adds a luxurious texture and richness to the casserole, keeping you feeling satisfied and energized without the need for empty carbs.
Cheddar Cheese
Cheddar cheese is another keto-friendly ingredient that shines in this dish. It not only provides a delicious cheesy flavor but also contributes valuable nutrients like protein, calcium, and vitamin B12. The combination of beef, mushrooms, and cheddar cheese creates a truly comforting and indulgent meal.

Step-by-Step Instructions for the Perfect Keto Beef and Mushroom Casserole
Ready to transform these incredible ingredients into a delectable keto-friendly casserole? Follow these easy steps:
Preheat and Prepare
First, preheat your oven to 375°F (190°C). This will ensure your casserole bakes to perfection.
Cook the Aromatics
In a large skillet, heat a drizzle of olive oil over medium heat. Add the diced onion and minced garlic, and sauté until they’re softened and fragrant. This step lays the foundation for the casserole’s delicious flavor.
Brown the Beef
Next, add the ground beef to the skillet and cook until it’s nicely browned. Be sure to drain any excess fat from the pan – we want to keep this dish as low-carb as possible.
Combine the Creamy Goodness
Now, it’s time to bring the casserole together. Stir in the sliced mushrooms, beef broth, heavy cream, thyme, salt, and pepper. Let the mixture simmer for 5-7 minutes, allowing the mushrooms to become tender and the flavors to meld.
Assemble and Bake
Transfer the savory beef and mushroom mixture to a greased 9×9-inch baking dish. Top it off with the shredded cheddar cheese, ensuring every bite is ooey-gooey and delicious. Pop the casserole in the oven and bake for 20-25 minutes, or until the cheese is melted and bubbly.
Serve and Enjoy
Once the Keto Beef and Mushroom Casserole is out of the oven, let it cool for a few minutes before serving. This allows the casserole to set and the flavors to truly shine. Pair it with a fresh green salad or your favorite low-carb sides for a complete and satisfying keto-friendly meal.

Variations and Customizations for Your Keto Beef and Mushroom Casserole
While this recipe is already a delicious keto masterpiece, you can easily customize it to suit your tastes. Consider adding other low-carb vegetables, such as spinach, zucchini, or bell peppers, for extra nutrition and variety. You can also experiment with different cheese options, like mozzarella or gouda, to change up the flavor profile.
For a heartier meal, you can substitute the ground beef with ground turkey or chicken. And if you’re in the mood for a bit of a kick, try adding a dash of cayenne pepper or a sprinkle of crushed red pepper flakes.
Meal Prep and Storage Tips for Your Keto Beef and Mushroom Casserole
One of the best things about this Keto Beef and Mushroom Casserole is that it’s perfect for meal prepping. You can make the entire casserole in advance and simply reheat it when you’re ready to enjoy it. To do this, assemble the casserole as directed, but don’t bake it. Cover and refrigerate the unbaked casserole for up to 3 days.
When you’re ready to bake, simply pop the casserole in the oven and follow the original baking instructions. For even easier meal prep, you can also freeze the unbaked casserole for up to 3 months. Just be sure to thaw it in the refrigerator before baking.
As for storing leftovers, the baked casserole will keep in the refrigerator for 3-4 days. To reheat, simply place individual portions in the microwave or oven until heated through. This makes the Keto Beef and Mushroom Casserole an incredibly convenient and satisfying meal option, perfect for busy weeknights or meal-prepping for the week ahead.

FAQs about Keto Beef and Mushroom Casserole
Can I use different types of mushrooms in the casserole?
Yes, you can definitely use different types of mushrooms in your Keto Beef and Mushroom Casserole. While traditional recipes often call for white button or cremini mushrooms, you can experiment with other varieties like shiitake, portobello, or oyster mushrooms. Each type brings its unique flavor and texture, adding depth to the dish. Just be sure to adjust the cooking time slightly if you’re using larger mushrooms, like portobello, to ensure they are cooked through.
How can I make the casserole spicier?
To add some heat to your Keto Beef and Mushroom Casserole, consider incorporating spicy elements. You can add crushed red pepper flakes, diced jalapeños, or even a splash of hot sauce to the beef while it cooks. Additionally, using a spicy cheese, like pepper jack, can enhance both the flavor and heat level. Just remember to adjust the other seasonings to balance the spice level according to your taste.
Is it possible to make this casserole in a slow cooker?
Absolutely! You can adapt the Keto Beef and Mushroom Casserole recipe for a slow cooker. Start by browning the ground beef with onions and garlic in a skillet and then transfer it to the slow cooker. Add the sliced mushrooms, cream, broth, and seasonings, then cook on low for about 4-6 hours. In the last 30 minutes of cooking, sprinkle the cheese on top and allow it to melt. This method can deepen the flavors and create a wonderfully comforting dish.
What are some tips for ensuring the casserole doesn’t become too watery?
To prevent your Keto Beef and Mushroom Casserole from becoming too watery, there are several steps you can take. First, make sure to properly drain any excess fat from the browned beef after cooking.

Finally, using a thicker heavy cream instead of a lighter variety can help maintain a creamy texture without adding too much liquid.
