  1. Preheat the oven to 375˚F.
  2. Heat olive oil in a large 12-inch skillet over medium-high heat.
  3. Add onions and cook for 2 minutes.
  4. Stir in garlic and cook for 20 seconds.
  5. Add ground beef; season with Italian Seasoning, paprika, salt, and pepper. Continue to cook, breaking up the meat with a wooden spoon, until the beef is completely browned.
  6. Add spinach in batches, stirring frequently, and cook for 1 more minute or until spinach is wilted.
  7. Remove from heat, drain liquid from the skillet, and set aside.
  8. In a 9×13-inch baking dish, combine cooked cauliflower rice, sour cream, butter, and dried basil. Stir and mix until completely combined and creamy. If sour cream and butter aren’t melting completely, stir in some milk. Ensure the cauliflower rice is warm enough to melt the butter.
  9. Add the prepared beef mixture to the baking dish; stir until everything is completely incorporated.
  10. Top with shredded cheese.
  11. Bake for 22 to 25 minutes, or until bubbly and the cheese is melted.
  12. Remove from the oven and let it stand for 7 to 10 minutes before cutting and serving.


  • Allow the casserole to sit for about 7 to 10 minutes before serving.
  • Avoid covering the casserole with foil before baking to let the cheese melt and bubble up.
  • Customize by adding more veggies like sautéed carrots or frozen peas.
  • Swap ground beef with turkey, pork, or Italian sausage if desired.
  • Prep a day ahead, store in the fridge, and bring to room temperature 15-20 minutes before baking.
