Ingredients for Low Carb Cauliflower Mac

Creating this wonderfully cheesy cauliflower low carb recipe is surprisingly simple, and you probably have most of the ingredients already! I love that it uses everyday items to transform humble cauliflower into a decadent dish.

1 head cauliflower, cut into bite-sized florets – aim for pieces roughly the same size so they cook evenly
1 tablespoon olive oil – just a little is needed to help the cauliflower soften
0.5 cup heavy cream – this is key for that luscious, creamy sauce
0.5 teaspoon mustard powder – it adds a subtle tang that really enhances the cheese flavor
0.5 teaspoon paprika – for a touch of color and mild, smoky flavor
4 ounces cheddar cheese, freshly shredded – shredding your own cheese melts much better than pre-shredded
4 ounces Colby Jack cheese, freshly shredded – a great melter that adds a mild, creamy flavor
2 ounces cream cheese, room temperature – make sure it’s soft so it blends smoothly into the sauce
Fresh chopped parsley, for garnish – adds a pop of freshness and color at the end

How to Make Low Carb Cauliflower Mac

Making this easy low carb cauliflower mac is a breeze, and I’m so excited for you to try it! It’s one of those dishes that feels indulgent but is actually packed with goodness.

Step 1: Start by prepping your cauliflower. Cut one head into bite-sized florets. It’s important they are all about the same size so they cook evenly.
Step 2: Heat 1 tablespoon olive oil in a large skillet over medium heat. Add your cauliflower florets. Sauté them for about 5 to 7 minutes, stirring occasionally. You want them to be tender-crisp, not mushy. I love the little bit of char they get!
Step 3: Pour in 0.5 cup heavy cream, 0.5 teaspoon mustard powder, and 0.5 teaspoon paprika. Stir everything gently to coat the cauliflower. This is where the magic starts to happen, creating a flavorful base for our cheesy sauce.
Step 4: Now, reduce the heat to low. This is crucial to prevent the cheese from burning or becoming oily. Add the 4 ounces cheddar cheese, 4 ounces Colby Jack cheese (both freshly shredded, remember!), and the 2 ounces cream cheese that’s at room temperature.
Step 5: Stir gently and continuously. Keep stirring until all the cheeses are melted and have formed a smooth, creamy sauce. You’ll know it’s ready when the sauce beautifully coats every single piece of cauliflower. This makes for such an easy low carb cauliflower mac!
Step 6: Serve your easy low carb cauliflower mac immediately. Garnish with fresh chopped parsley for a pop of color and freshness. Enjoy this delicious, guilt-free comfort food!
