Brief Introduction
This cauliflower mac and cheese is the ultimate comfort food makeover. Born out of a craving for cheesy pasta on a weeknight, this version swaps noodles for cauliflower florets—keeping all the creamy goodness with a fraction of the carbs. It’s rich, simple, and ready in under 30 minutes—a true weeknight hero.
Step-by-Step Cooking Guide
1. Boil the Cauliflower
Cook the cauliflower florets in salted boiling water until tender but still slightly firm (about 5–6 minutes).
Tip: Overcooking makes them soggy—aim for fork-tender.
2. Prepare the Cheese Sauce
In a medium saucepan, melt the butter and whisk in heavy cream. Stir in Dijon mustard, garlic powder, and paprika for depth.
Tip: Whisk constantly to avoid scalding the cream.*
3. Melt in the Cheeses
Add shredded cheddar and cubes of cream cheese to the warm sauce. Stir until silky and smooth.
Troubleshooting: If the sauce separates, remove from heat and whisk vigorously until it re-emulsifies.
4. Combine and Serve
Add the drained cauliflower to the sauce and stir gently until coated. Sprinkle with black pepper before serving.
Optional: Top with Parmesan and bake under a broiler for 3–5 minutes for a golden crust.
