How to Make Keto “Tatertot” Casserole

Step 1: Prepare the Cauliflower

Start by cutting fresh cauliflower into small florets that resemble mini tatertots. Toss them lightly with olive oil, salt, and paprika, then roast in the oven at 400°F for about 20 minutes or until they’re golden and crispy.

Step 2: Cook the Ground Beef Mixture

While cauliflower roasts, heat a skillet with butter or olive oil over medium heat. Sauté diced onions and minced garlic until fragrant, then add ground beef and cook until browned. Stir in Worcestershire sauce, salt, pepper, and a bit of paprika for warmth.

Step 3: Make the Creamy Sauce

In a small saucepan, warm the heavy cream gently, then mix in shredded cheddar cheese until melted and smooth. Pour this cheesy sauce over the cooked beef and stir to combine thoroughly.

Step 4: Assemble the Casserole

In a baking dish, layer the cooked ground beef and creamy cheese mixture first, then top evenly with the roasted cauliflower “tatertots.” Sprinkle additional shredded cheese on top for a perfect golden crust.

Step 5: Bake Until Bubbling

Bake the casserole at 375°F for about 15 minutes, or until the cheese is bubbly and golden on top. Let it rest a few minutes before serving to allow the layers to set beautifully.

Pro Tips for Making Keto “Tatertot” Casserole

Roast cauliflower well: Ensure florets are dry and spaced apart for maximum crispiness.
Use sharp cheddar: Bold flavors melt best and keep the dish rich.
Don’t skip resting: Letting the casserole cool slightly improves slicing and serving.
Customize seasoning: Adjust paprika and Worcestershire to personal taste for added depth.
Use fresh ingredients: Fresh cauliflower and real cream make a notable difference in texture and flavor.

Instructions
