Ingredients

  • Cooked Broccoli: Fresh broccoli is ideal for this dish—steam it until tender but still crisp. If you’re short on time, frozen broccoli works too; just cook and drain it thoroughly to remove excess moisture.
  • Creamy Base Trio: This mix of cream cheese, sour cream, and mayonnaise makes a rich, smooth texture. It can replace regular canned soups. This combination adds depth and creaminess to the casserole.
  • Cheese: Opt for shredded cheddar cheese for its sharp, tangy flavor. For a twist, mix in Monterey jack cheese to add a mild, melty texture that complements the dish perfectly.
  • Seasonings: A mix of dried minced onion or onion powder, garlic powder, dried parsley, kosher salt, and black pepper adds flavor. This gives the casserole a tasty and balanced taste.

How To Make Keto Broccoli Casserole

Step 1: Prepare the Creamy Mixture

In a large mixing bowl, combine the cream cheese, sour cream, and mayonnaise until smooth. Add the dried minced onion (or onion powder), garlic powder, dried parsley, kosher salt, and black pepper. Mix well to ensure you distribute the seasonings evenly. Stir in half of the shredded cheddar cheese, creating a rich and flavorful base for your casserole.

Step 2: Add the Broccoli

Gently fold the steamed broccoli into the creamy mixture. Be careful not to overmix; this action keeps the broccoli intact and packs every bite with texture and flavor. Once combined, transfer the mixture to a greased casserole dish, spreading it out evenly.

Step 3: Top with Cheese

Sprinkle the remaining shredded cheddar cheese over the top of the broccoli mixture. This creates a golden, cheesy crust as it bakes, adding a delicious finishing touch to your casserole.

Step 4: Bake to Perfection

Preheat your oven to 375°F (190°C). Put the casserole dish in the oven.

Bake it for about 20 minutes. Melt the cheese until it becomes bubbly and lightly golden on top. Remove from the oven and let it cool slightly before serving.

Storage Instructions

To store your Keto Broccoli Casserole, let it cool completely before placing it in an airtight container. You can keep it in the refrigerator for up to 3-4 days, making it a convenient option for meal prep or leftovers.

When you are ready to enjoy it again, reheat the casserole in the oven. Set the temperature to 350°F (175°C). Heat it until it is warm and the cheese is bubbly.

Alternatively, you can microwave individual portions for a quick and easy meal.

Keeping your casserole in the fridge helps it stay fresh and tasty. Ready whenever you want a delicious low-carb meal!

Tips for Achieving Maximum Flavor

To elevate the taste of your Keto Broccoli Casserole, start by using fresh, high-quality ingredients. Steam the broccoli just until tender to retain its vibrant color and slight crunch, avoiding overcooking.

For the creamy base, soften the cream cheese to blend it smoothly with the sour cream and mayonnaise. Opt for sharp cheddar cheese or a mix of cheeses like Monterey Jack for a richer, more complex flavor.

Don’t skimp on the seasonings—adjust the garlic powder, onion powder, salt, and pepper to suit your taste preferences.

Finally, let the casserole sit for a few minutes after baking. This helps the flavors mix. You will end up with a dish that is full of delicious, savory goodness!
