How to Make Keto Tatertot Casserole Low Carb
Step 1: Sauté the Aromatics
Start by preheating your oven to 375°F (190°C). Heat olive oil in a large skillet over medium, then toss in your finely chopped onion and garlic. Sauté until they’re soft and fragrant—about 2 to 3 minutes. This step is all about building a sweet, savory foundation for your Keto Tatertot Casserole Low Carb.
Step 2: Brown the Beef and Season
Add the ground beef to your skillet along with Worcestershire sauce, salt, and black pepper. Cook, breaking the beef up as it browns, until there’s no pink left. Drain off any extra grease so your casserole isn’t swimming—it should be rich, not oily!
Step 3: Make it Creamy
Stir in the cream cheese and heavy cream. As the cream cheese melts, you’ll notice the mixture turning irresistibly creamy. This luscious sauce is what sets Keto Tatertot Casserole Low Carb apart from the rest!
Step 4: Add Cheese and Cauliflower
Mix in 1 cup of shredded cheddar and the chopped cauliflower florets. The cheese melts into the sauce, while the cauliflower adds extra substance and sneaks in some veggies without changing the flavor.
Step 5: Assemble the Casserole
Grease a 9×9-inch or 8×8-inch baking dish and pour in your beef mixture. Spread it out so every bite gets an even layer of creamy filling. Then, arrange the cauliflower tots in a single layer on top—don’t worry if they’re not perfectly aligned, rustic is charming!
Step 6: Add the Final Cheesy Layer
Sprinkle the remaining ½ cup of shredded cheddar evenly over the tots. This gives the casserole its bubbly, golden top and delivers that classic, gooey finish you crave.
Step 7: Bake and Rest
Pop your dish into the oven and bake for 25 to 30 minutes, or until everything is bubbly and golden. Let it rest for 5 minutes before serving—this helps the casserole set and makes serving tidy squares a breeze.
How to Serve Keto Tatertot Casserole Low Carb

Garnishes
A sprinkle of chopped parsley or green onions adds a fresh pop of color and flavor, balancing out the richness. If you want to get playful, a dash of smoked paprika or a few sliced jalapeños on top can add even more personality to your Keto Tatertot Casserole Low Carb.
Side Dishes
This casserole is filling enough to stand on its own, but if you’re looking for something extra, try it with a crisp green salad, roasted asparagus, or sautéed spinach. These light, bright sides round out the meal and keep everything feeling fresh.
Creative Ways to Present
For family-style comfort, serve your Keto Tatertot Casserole Low Carb straight from the baking dish. Hosting a crowd? Cut it into small squares and plate with toothpicks for keto-friendly party bites. Or, serve individual portions in ramekins for a personal touch—everyone loves their own mini casserole!
Make Ahead and Storage
Storing Leftovers
Leftover Keto Tatertot Casserole Low Carb keeps beautifully in the fridge for up to 4 days. Transfer cooled portions to airtight containers so they stay fresh and don’t pick up any fridge odors. This dish is just as delicious reheated, making lunch the next day something to look forward to!
Freezing
If you want to freeze the casserole, assemble it right up to the point before baking. Wrap tightly with plastic wrap and foil, then freeze for up to 2 months. When ready to enjoy, thaw in the fridge overnight and bake as directed (you may need to add a few extra minutes to the bake time).
Reheating
To reheat, simply pop individual servings in the microwave until hot, or warm the whole casserole in a 350°F oven for 15–20 minutes. The cauliflower tots re-crisp nicely in the oven, so if you love that golden top, that’s the way to go!
