Ingredients

- Onion: You can use sweet onion or plain white onion. The caramelized onions ia richness to this dish with their subtle sweetness.
- Prosciutto: The crispy prosciutto adds a nice salty element. If you cannot find prosciutto, you can also use bacon, pancetta, ham, or even salami. (Try this Prosciutto Chicken and Broccoli Sheet Pan Meal)
- Cheese: For the rich, creamy cheese sauce on this ket Mac and cheese, I used sharp cheddar, goat cheese and parmesan. Some other good choices are cream cheese, American, smoked mozzarella, gruyere, fontina, and havarti. (Try this Keto Cheese Sauce)

Caramelized Onion and Prosciutto Mac and Cheese

- Yield: 6 Servings 1x
- Diet: Gluten Free
Description
This Caramelized Onion and Prosciutto Keto Mac and Cheese is the ultimate in low carb comfort food. The steamed cauliflower, scratch made cheese sauce, rich caramelized onions, crispy prosciutto cheese are a match made in heaven.
Ingredients
Units
Scale
- 1 large head cauliflower, cleaned and trimmed (but left whole)
- 1 tablespoon olive oil
- 4 tablespoons butter, divided
- 1 medium onion, diced
- 3 cloves garlic, minced
- 1 cup heavy cream
- ½ cup grated Parmesan cheese, extra for garnish
- 1 cup shredded sharp cheddar cheese, extra for garnish
- ¼ cup goat cheese
- ¼ teaspoon black pepper
- 6 ounces prosciutto, diced and cooked crisp
- fresh chopped parsley, for garnish
Instructions
- Preheat oven to 350°F.
- In a large covered pot with 1 inch of water, steam the cauliflower on high heat until fork tender. About 15 minutes.
- Remove from heat, drain water and allow cauliflower to remain in the hot pot to draw out excess moisture. (This is important… Otherwise you might end up with mac and cheese soup)
- Place head of cauliflower in an 8 x 8 casserole dish. Using a fork, slightly mash the cauliflower to break it all apart.
- In a large sauté pan over medium heat, heat the olive oil and 2 tablespoons of the butter. Once the butter is melted, add the onions to the pan and sauté until they have a nice caramel color. Remove the onions from pan and set aside.
- To the same pan add remaining butter and garlic. Sauté until the garlic is fragrant. Add the heavy cream and Parmesan cheese. Stir continuously until the Parmesan is melted and the sauce begins to come to a boil. Mix in cheddar cheese, goat cheese and black pepper. Stir until cheeses are melted and well incorporated into the sauce. Reduce heat to low and allow the sauce to thicken as it simmers, about 5 minutes.
- Pour cheese sauce evenly over top of the cauliflower. Layer caramelized onions on top of sauce. Lastly, layer crispy prosciutto on top of the caramelized onions. Sprinkle with remaining cheese and bake for 15 minutes.
- Garnish with parsley before serving.
Notes
- net carbs per serving: 7g
- Storage: Store leftovers in the refrigerator for up to 4 days.
- Reheating: I recommend reheating this in a pan on the stove top or in the oven. You may need to mix in a little extra cream to help bring it back to life

Not a fan of cauliflower, but I think I might try subbing with spaghetti squash. Wish me luck, any tips?
Dan says
No tip for you, but I had the same thought. How did it turn out with spaghetti squash?
Christina Harris says
This recipe was AMAZING!!!!! The one tough part about living this lifestyle is that the sides are hard when you have a husband who is not a fan of many vegetables - so of course he gets sick of cauliflower. He devoured this!
Thank you, thank you, thank you for all your recipes, I share this website with everyone!

This is the recipe that made me think, "Hmmm, I guess I will try the meal Plan."
I had to call it Caramelized Onion and Prosciutto Macish Cheese as my children become VERY upset when they find out that I have substituted a veg for their noodles. However, if they know in advance they will try anything. They loved it and my husband and I did too.
I did substitute frozen cauliflower florets as I had a bag in the freezer.
Peace Love and Low Carb says
So happy the whole family enjoyed it!! It's a favorite in our household also.
Kris says
Could milk be substituted for the heavy cream to cut down some on the calories?
Peace Love and Low Carb says
It will make the sauce watery, but you can always try it.
Christa Wagner says
Just made this last night and it was GREAT! I love substituting cauliflower for rice or potatoes but I hate the taste of cauliflower! This will definitely be in our rotation! Can't wait to try more of your recipes in my cookbook!

I was scrolling through and found an amazing recipe with diacon radish "rice", chicken, Asian seasonings..... I got distracted and now I can't find it again. Will you republish that recipe?
Thank you in advance!
christie smith says
ok i'm really curious.... does this really compare to the real thing? i won't use dreamfields anymore, since i've decided that's all a pipe dream. i love my pasta, though, and i'm really scared of trying any recipe with cauliflower! (i'm 50 years old and have only started eating veggies in the last four years, and my palate is still pretty limited in that area.)
