Some nights call for food that feels like a warm hug. That’s usually when I reach for this keto beef casserole with ground beef. It’s one of those dishes that fills the kitchen with a rich aroma—garlic and herbs dancing in the air, the smell of melting cheese slowly creeping out as it bakes. I remember the first time I made it; I was a little distracted by texts buzzing on my phone, so I might have forgotten to stir the skillet a few times. Yet, the casserole still came out golden and bubbly, with that perfect crust of Parmesan on top. The soft zucchini and cauliflower bits add just enough texture, keeping things interesting without stealing the spotlight from the creamy cheddar sauce. It’s the kind of meal that doesn’t demand fuss but rewards you with cozy satisfaction.

Ingredients
1 pound ground beef
1 medium onion, diced
3 cloves garlic, minced
1 medium zucchini, diced
1 cup cauliflower florets, chopped into small pieces
1 cup mushrooms, sliced
1 cup shredded cheddar cheese
1/2 cup heavy cream
1/2 cup sour cream
1/2 cup beef broth
2 tablespoons olive oil
1 teaspoon dried oregano
1 teaspoon dried thyme
1/2 teaspoon smoked paprika
Salt, to taste
Black pepper, to taste
2 tablespoons grated Parmesan cheese
Instructions
Preheat the oven to 375°F (190°C).
Heat olive oil in a large skillet over medium heat.
Add diced onion and cook for 3-4 minutes until translucent.
Add minced garlic and cook for 1 minute until fragrant.
Add ground beef to the skillet, breaking it apart with a spatula. Cook until browned and no longer pink, about 7-8 minutes. Drain excess fat if necessary.
Stir in diced zucchini, chopped cauliflower, and sliced mushrooms. Cook for 5 minutes until vegetables start to soften.
Add dried oregano, dried thyme, smoked paprika, salt, and black pepper. Stir well to combine.
In a separate bowl, whisk together heavy cream, sour cream, and beef broth until smooth.
Pour the cream mixture into the skillet with the beef and vegetables. Stir to combine and cook for 2-3 minutes until slightly thickened.
Remove the skillet from heat and stir in 3/4 cup shredded cheddar cheese until melted and well combined.
Transfer the mixture into a greased 9×9-inch casserole dish.
Sprinkle the remaining 1/4 cup shredded cheddar cheese and grated Parmesan cheese evenly on top.
Bake in the preheated oven for 20-25 minutes until the casserole is bubbly and the cheese on top is golden brown.
Remove from oven and let cool for 5 minutes before serving.
Kitchen Notes:
This recipe comes together easily with just a skillet and a casserole dish—no fancy gadgets needed. I usually serve it with a green salad or some roasted asparagus to keep things light. Sometimes I swap out mushrooms for bell peppers, but honestly, I haven’t tested every veggie combo yet, so your mileage may vary. If you want a bit more tang, a dollop of sour cream on top before serving can be nice. For a bit of extra crunch, sprinkling some crushed pork rinds or nuts on top before baking adds a fun texture twist.
FAQ
Can I make this ahead of time? Absolutely. It keeps well in the fridge for a few days and reheats nicely in the oven or microwave. Freezing is also an option, just thaw overnight before warming up.
Is it okay to use different cheeses? Sure, but cheddar and Parmesan are what make the sauce sing. Mixing in some mozzarella or pepper jack could work, but might change the flavor profile.
Can I add more veggies? Definitely. Just keep in mind that watery veggies might make the casserole a bit looser, so you might want to cook them down first.
