This low carb mock Yumasetti bake is my shortcut answer to those nights when I want cozy Midwestern comfort food without boiling noodles or dirtying a bunch of pans. Instead of pasta, we use raw cauliflower florets as the base, then spread one creamy, cheesy ground beef mixture over the top and let the oven do the work. It hits all the classic casserole notes—savory, tangy, cheesy—while staying low carb and weeknight-friendly. If you grew up on church potlucks and hotdish, this will feel very familiar, just a little lighter and a lot easier.
Serve this low carb mock Yumasetti with a simple green salad tossed in a tangy vinaigrette to balance the richness, or add some steamed green beans or roasted broccoli on the side. It’s hearty enough to be a full meal on its own, but a side of crusty low carb bread or a slice of keto-friendly garlic toast is great for scooping up the extra sauce. For a quick worknight dinner, I like to pair it with bagged salad and call it done, and for leftovers, it reheats well for easy lunches the next day.
Low Carb Mock Yumasetti Cauliflower Bake
Servings: 6

Ingredients
1 1/2 pounds ground beef (80–90% lean)
1 medium head cauliflower, cut into small florets (about 6 cups)
1 cup sour cream
6 ounces cream cheese, softened and cubed
2 cups shredded cheddar cheese, divided
1/2 medium yellow onion, finely chopped
2 cloves garlic, minced
1 teaspoon kosher salt, divided
1/2 teaspoon black pepper, divided
1/2 teaspoon onion powder
1/2 teaspoon garlic powder
1/2 teaspoon dried parsley (optional)
1 tablespoon olive oil or butter (for sautéing, if needed)
Nonstick cooking spray or 1 teaspoon butter (for greasing the baking dish)
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with nonstick spray or butter.
Prep the cauliflower by cutting it into small, bite-size florets so it cooks through in the oven. Spread the raw cauliflower florets evenly in the bottom of the prepared baking dish and season them lightly with a pinch of salt and pepper. Set aside.
In a large skillet over medium-high heat, cook the ground beef, breaking it up with a spatula as it browns. If your beef is very lean or your pan is dry, add the olive oil or butter to help it along.
When the beef is about halfway cooked, add the chopped onion, minced garlic, 1/2 teaspoon of the salt, and 1/4 teaspoon of the black pepper. Continue cooking until the beef is no longer pink and the onions are softened, about 5–7 minutes. Drain off any excess grease if necessary and return the beef mixture to the skillet.
Reduce the heat to low. Add the cream cheese cubes to the hot beef mixture. Stir slowly until the cream cheese melts and starts to coat the beef.
Stir in the sour cream, 1 1/2 cups of the shredded cheddar cheese, onion powder, garlic powder, dried parsley (if using), and the remaining 1/2 teaspoon salt and 1/4 teaspoon pepper. Mix until everything comes together into one thick, creamy mixture. Taste and adjust seasoning if needed.
Place the baking dish with the raw cauliflower on your counter. Using a spatula or the back of a large spoon, spread this one creamy ground beef and cheese mixture evenly over the raw cauliflower florets, making sure most of the florets are covered. It’s okay if a few tips peek through; they’ll roast up nicely.
Sprinkle the remaining 1/2 cup shredded cheddar cheese evenly over the top of the creamy layer.
Cover the baking dish tightly with foil and bake at 375°F (190°C) for 25 minutes to help the cauliflower steam and soften.
Remove the foil and continue baking for another 15–20 minutes, or until the cauliflower is tender when pierced with a fork and the top is bubbly and lightly golden.
Let the casserole rest for 5–10 minutes before serving so it can set up slightly and is easier to scoop. Serve warm straight from the baking dish.
Variations & Tips
Use ground turkey or ground chicken instead of beef for a lighter version; just add an extra teaspoon of olive oil and a pinch more salt since poultry is milder. For a bit of a classic Yumasetti vibe, stir 1/4 cup of chicken or beef broth into the creamy mixture to loosen it slightly and make it more sauce-like, or add 1/4 cup grated Parmesan for extra savory depth. If you like a little heat, mix 1/4 teaspoon crushed red pepper flakes or a few dashes of hot sauce into the creamy beef mixture before spreading it over the cauliflower. Swap part of the cheddar for Monterey Jack, Colby Jack, or pepper jack for a different flavor profile. To make it extra veggie-heavy, tuck a handful of raw sliced mushrooms or a cup of frozen peas (thawed and patted dry, if you’re not strict low carb) over the cauliflower before adding the creamy mixture. For meal prep, assemble the dish up to the point of baking, cover tightly, and refrigerate for up to 24 hours; when ready to cook, add 5–10 minutes to the covered bake time to account for the cold dish. Leftovers keep well in the fridge for 3–4 days and reheat nicely in the microwave or a 350°F oven, making this a great make-ahead lunch option.
