Quick & Easy

With simple ingredients and a quick prep process, this keto casserole is easy to prepare even on busy weekdays. It’s also a great make-ahead option. Simply prepare it in advance and refrigerate until you’re ready to bake.

Ingredients & Substitutions: 

• Cauliflower – Use fresh cauliflower cut into florets. If you’re in a pinch, frozen cauliflower works too, but fresh will give a firmer texture.
• Cheddar cheese – Sharp cheddar brings a rich, tangy flavor to the dish. You can substitute with mild cheddar or a blend of cheeses.
• Mozzarella cheese – For that gooey, melt-in-your-mouth texture. You can use a low-moisture mozzarella for a firmer melt.
• Parmesan cheese – Adds a salty, nutty flavor to the casserole. Grana Padano or Pecorino Romano can be substituted.
• Sour cream – For a creamy and tangy finish. Greek yogurt or crème fraîche can be used in place.
• Double cream – Heavy cream will work as a substitute if you can’t find double cream.
• Cream cheese – Softened to combine smoothly with the other ingredients. Full-fat cream cheese is preferred, but you can use light cream cheese as a lower-calorie option.
• Garlic – Fresh garlic gives the best flavor, but garlic powder is a substitute.
• Butter – Melted butter helps grease the baking dish and adds richness to the casserole.
• Onion powder – For a subtle, savory flavor.
• Chives – Optional garnish for added color and flavor.

Step-by-Step Procedure

1. Preheat the Oven
   Preheat your oven to 350°F (175°C). This will ensure that your casserole cooks evenly.
2. Prepare the Cauliflower
   Bring a large pot of salted water to a boil. Add the cauliflower florets and cook for about 5-7 minutes, until they are tender but still firm. Drain well and set aside.
3. Make the Cheese Sauce
   In a saucepan over medium heat, combine the cream cheese, sour cream, chicken or vegetable broth, minced garlic, onion powder, salt, pepper, and paprika. Whisk everything together until the mixture is smooth and heated through. Remove from heat and stir in 1 cup of shredded cheddar cheese and the grated Parmesan cheese until melted and well combined.
4. Combine Cauliflower and Cheese Sauce
   In a large mixing bowl, add the cooked cauliflower and pour the cheese sauce over it. Gently stir to coat the cauliflower evenly with the sauce.
5. Transfer to Baking Dish
   Pour the cauliflower mixture into a greased 9×13 inch baking dish. Spread it out evenly. If you like, sprinkle additional shredded cheddar cheese on top for extra cheesiness.
6. Bake the Casserole
   Place the baking dish in the preheated oven and bake for about 25-30 minutes, or until the cheese is bubbly and slightly golden on top.
7. Garnish and Serve
   Once out of the oven, let it cool for a few minutes before serving. If desired, sprinkle chopped green onions or chives on top for a fresh touch.
