This creamy, cheesy tangy microwave cauliflower recipe is one even cauliflower haters will love. Cooking a whole head of cauliflower in the microwave is a super easy side dish. Topped with a mixture of mayonnaise, mustard and slices of American cheese.
About This Recipe and Why It Works
I’ve always claimed that even cauliflower haters would cozy up to this recipe. And being married to one, I can attest that even the Ranch Hand likes this one.
Way back in the dark ages, when microwave ovens were first available for purchase for our home kitchens, I got one for Christmas.
It was a Radar Range and I wish I had a photo of it. Compared to our sleek modern versions, it’s probably somewhat laughable. The appliance came with a cookbook illustrating how you could magically prepare anything from pot roast to desserts …in a flash.
This new appliance seemed so daunting, I was compelled to take a class offered at our local Sears store. A demonstration type class, that lasted a couple of hours.
This is where I learned of this microwave cauliflower recipe, a recipe to microwave a whole head of cauliflower. I’ve been making it ever since, and regularly for over 40 years.
To steam cauliflower in the microwave yields a tender texture and sweet flavor.
Once the topping of mayonnaise, mustard and American cheese are added the tangy, creamy cheesy flavors truly enhance the entire experience.
If you’re looking for easy cauliflower recipes, and looking for whole cauliflower recipes, you must give this one a try. It’s so easy, creamy and cheesy.
Ingredients To Make Microwave Cauliflower
- Cauliflower: 1 whole head. Any size will do. I always grab a large sized head of cauliflower for more servings and leftovers.
- Mayonnaise: A good quality mayo works well for cooking. Dukes or Best Foods are good here.
- Mustard: Plain yellow prepared mustard.
- Onion: Fine diced sweet or yellow onion.
- American Cheese: Individual slices of American Cheese is a beautiful melting cheese.
- Cheese: Substitute grated cheese for the American Slices. A medium cheddar works well. I highly recommend grating the cheese yourself as the pre-grated bags of cheese contain ingredients to keep it from sticking together in the bag. In turn, those ingredients will keep the cheese from melting as well.
- Onion: To make things even easier, I’ve used dried onion flakes for this recipe. Just mix in the flakes and let it sit a few minutes to soften before cooking.
How To Make This Easy Microwave Cauliflower with Cheese
Step 1: How to remove the cauliflower core. Using a sharp large chef knife, cut around the core area and remove the protruding core and outer leaves of the cauliflower.
Step 2: Ready to microwave: Place the cauliflower, core side down in a deep 2 – 3 quart microwavable casserole dish. Add 2 tablespoons of water, cover and cook for 8 – 10 minutes on high.
Step 3: Make the cheese sauce. While the cauliflower is cooking, combine the mustard, mayo, and onions and blend together with a fork.
Step 4: Remove the cooked cauliflower from the microwave and spoon the sauce over the top.
Step 5: Add the Sauce: Using the back of a spoon, coat the cooked cauliflower with the mayo, mustard sauce. Make sure to coat the cauliflower as far down the sides as you can.
Step 6: Add the Cheese: Place the slices of American Cheese on the top of the sauced cauliflower. Alternate the angle of the cheese slices for even melting.
Step 7: Cover the pan with the lid and return the cauliflower to the microwave. Cook on high for 2 minutes to melt the cheese and heat the mayonnaise mustard sauce. Let the cauliflower stand, covered, for two minutes before slicing.
Step 8: How to Serve Microwave Cauliflower: Using a sharp knife, slice the cauliflower in wedges and serve immediately.
Tips for Success
By the way, did you read that the Millennials are throwing American Cheese out of their diets? If you are one that simply doesn’t like processed American cheese, you can most certainly substitute grated cheddar cheese. But it doesn’t melt as beautifully.
I tried cooking this in my Instant Pot and it took longer than in cooking cauliflower in the Microwave. Due to pre-heating, coming to pressure, and releasing pressure, the microwave had it beat by about eight minutes. Score one for the microwave. But yes, you can cook a whole head of cauliflower in the Instant Pot. Just follow the same steps for the microwave recipe.
Microwave powers vary as do the size of a full head of cauliflower. After 8 minutes of cooking the cauliflower in the microwave, remove it and use a fork to test its doneness. If the fork inserts into a tender vegetable, the cauliflower is done. If it feels too crisp, return to microwave and cook 1 – 2 minutes longer.
Did your perfect deep casserole dish not come with a lid? Simple, just cover tightly with plastic wrap. Using a fork , poke a few holes in the plastic wrap.
- Store any leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, simply microwave in 20 second increments at 50% power.
