I'll happily admit it: side dishes are often my favorite part of the meal. This Keto
Broccoli Casserole is one I make again and again, with tender broccoli coated in
creamy ranch and cream cheese, then loaded with cheddar and Parmesan. It's
cheesy, comforting, and easy enough for a weeknight, but holiday-worthy, too.

This Broccoli Cheese Casserole takes me back to childhood, but in a creamier cheesier way.
This is a fresher take on traditional broccoli casserole, which is often made with canned soup.
It's one of my favorite kid-friendly casserole recipes that comes together easily.
How to Make Keto Broccoli Casserole

- First, preheat your oven to 350 degrees. Bring a large pot of water to a boil. Fill another bowl with ice water. Add the broccoli to the boiling water and cook for 1 ½ minutes. Drain and immediately plunge in a bowl of ice water. Drain and transfer to a dry bowl.

2. Next, spray a small skillet with oil and add the onions. Cook for 6 minutes, and then add the garlic. Transfer to the bowl with the broccoli. While the onions are cooking, combine the cream cheese, ranch, and cayenne pepper in the food processor. Process until smooth. Toss with the broccoli mixture and transfer to an 8 x 8 casserole dish.

3. Finally, top with cheese and bake for 25 minutes.

Have you tried to make this in an Air Fryer and, if so, how did you adjust the total baking time? I can figure out the 'saute' of the onions and garlic.
Wendy Polisi says
I haven't tried it. In general you want to reduce your temperature by 25 to 50 degrees, and cut the baking time by around 30%.
