How To Make Keto Broccoli Casserole

Making this keto broccoli casserole recipe is simple and doesn’t take much prep work! You’ll start by making the keto cheese sauce.

In a large saucepan, sauté the onions with the butter until they’re translucent on medium-high heat.

Then you’ll add in the spices, and while whisking, pour in the heavy whipping cream. Continue whisking until the sauce starts to thicken, then reduce to medium heat.

Next, you’ll add the cream cheese, parmesan, and part of the shredded cheddar cheese. Stir until the cheeses melt and combine into the sauce. At this point, you can take your sauce off the heat and set it aside.

Then, boil water in a 5-quart pot, add your broccoli florets, and cook for about 2 to 3 minutes. Once the broccoli is slightly tender, drain the broccoli well.

Note that the steamed broccoli will continue to cook in the oven in the casserole, so do not overcook.

In a large bowl, add the broccoli and half the cheese sauce and combine well.

Transfer this mixture to your prepared casserole dish, top with the remaining cheese sauce and shredded cheese, and bake for 30 to 40 minutes until the cheese is browned.

If you have any, you can store leftovers in the refrigerator in an airtight container for up to 3 days or even freeze for up to 3 weeks.
