Getting Started with Making Creamy Broccoli Casserole (Without Baking Mix)
We’re going to approach this recipe in a couple of stages–making the sauce and making the casserole.
Prep Work and Cooking the Broccoli
Before we get into the sauce making, we’re going to spray a 9×13-inch casserole dish with nonstick cooking spray and preheat the oven to 350°F.
We’ll dice 2 cups of Onion and set it aside. If you’re mincing your own garlic, you’ll want to do that now as well. You need 2 tablespoons of minced garlic or about 4 cloves.
You’ll want to trim the ends of your broccoli florets if they need it. Then we’re going to cook the broccoli the easy way by steaming it in the microwave until it’s just tender (about 3 minutes). After that, we’ll coarsely chop the broccoli and spread it evenly into the prepared baking dish. Now we’ll set that aside for the moment.
Making the Creamy Sauce
Next we’ll heat 1 tablespoon of Unsalted Butter and 2 tablespoons of Avocado Oil in a large sauté pan over medium-high heat. You’ll add the onion to the pan, stirring frequently until they’re soft and translucent (about 3 – 5 minutes). Then we’ll incorporate the garlic and cook until fragrant, about 60 seconds more.
Now to thicken things up, we’ll sprinkle ⅓ cup of Almond Flour and ¼ teaspoon of Xanthan Gum over the vegetables and cook for 1 minute. While stirring, we’ll slowly pour in 3.5 cups of Chicken Broth. Then we’ll continue to cook it down, stirring occasionally, until thickened, about 3 minutes.
Next, we stir in 8 ounces of Cream Cheese, 2 teaspoons of Worcestershire Sauce, ¾ teaspoon of Ground Black Pepper, and ½ teaspoon of Kosher Salt. You’ll keep cooking it, stirring until smooth, about 2 minutes.
Once it’s thickened, we’ll remove it from the heat and stir in 1 1/2 cups of the Shredded Cheese and 1/3 cup of Mayonnaise.
Assembling and Baking the Creamy Broccoli Casserole
Finally, we’ll pour the cheese sauce over the broccoli and spread the Crushed Pork Rinds or Keto Bread Crumbs (your choice) evenly over the broccoli mixture. Then you can top the casserole with the remaining 1/2 cup cheese.
We’ll bake the Creamy Broccoli Casserole at 350°F until the cheese is melted and the sauce is bubbling around the edges, about 25 to 30 minutes. Serve warm and enjoy.
