Ingredients

Kosher salt & freshly ground black pepper
1 medium head cauliflower, trimmed, cored, and cut into very small florets (about 6 cups)
1 tablespoon unsalted butter
1 medium onion, finely chopped
1⁄2 cup plus 2 tablespoons whole milk
4 ounces cream cheese, cut into pieces
1 1⁄4 cups lightly packed coarsely grated cheddar cheese (4 ounces)
1⁄2 cup lightly packed coarsely grated gruyere (2 ounces)
1 teaspoon Dijon mustard
1⁄2 garlic clove, finely grated
1⁄2 teaspoon cayenne, plus more to taste
1⁄4 teaspoon freshly grated nutmeg, plus more to taste
2⁄3 cup finely chopped toasted almonds
1⁄4 cup finely chopped chives

Equipment Needed

Large Pot
Large Skillet
Broiler

Instructions

Begin by preparing the cauliflower. Bring a large pot of generously salted water to a boil. Add the cauliflower florets and cook until they are crisp-tender, which should take approximately 1 minute. It’s crucial not to overcook them at this stage, as they will continue to cook in the cheese sauce. Once done, drain the cauliflower thoroughly and set it aside.
Now, let’s create the base for our luscious cheese sauce. In a large skillet set over medium-high heat, melt the butter. Watch carefully as the butter melts; as soon as the foaming subsides, add the finely chopped onion. Season generously with salt and pepper.
Sauté the onions, stirring occasionally, until they become translucent. This usually takes around 5 minutes. Make sure the onions don’t brown excessively; you want them to be softened and sweet.
Reduce the heat to low, add the milk and cream cheese. Cook, stirring constantly, until the cream cheese is completely melted and incorporated into the milk, creating a smooth base for the sauce.
Now for the stars of the show: the cheeses. Add the cheddar cheese, gruyere, Dijon mustard, garlic, cayenne, and nutmeg to the skillet.
Continue to cook, stirring frequently, until all the cheese is melted and the sauce is smooth and creamy. This should only take a few minutes. Be careful not to overheat the sauce, as it can become grainy.
Season the cheese sauce to taste with salt and pepper. If you want to increase the spice level, add more cayenne, or if you want to add some warmth to the sauce, add more nutmeg, if desired.
Add the cauliflower to the skillet and gently fold it to coat it evenly with the cheese sauce. Ensure that every floret is covered in the creamy goodness.
Transfer the cauliflower mixture to a broiler-safe dish or leave in the skillet if broiler-safe.
Broil the mac and cheese until the top is deeply golden brown and bubbling. This usually takes about 2-3 minutes, but keep a close eye on it to prevent burning. The broiler can be intense, and you want to achieve that perfect browned crust without scorching the dish.
Remove from the broiler and garnish generously with the finely chopped toasted almonds and fresh chives.
Serve immediately and enjoy the explosion of flavors!

Expert Tips & Tricks

Toast your almonds! Toasting the almonds brings out their nutty flavor and adds a lovely crunch. To toast, spread them on a baking sheet and bake at 350°F (175°C) for 5-7 minutes, or until golden brown.
Grate your own cheese. Pre-shredded cheese often contains cellulose, which can prevent it from melting as smoothly. Grating your cheese fresh ensures a creamier sauce.
Spice it up! If you’re a fan of heat, feel free to add more cayenne pepper or even a pinch of red pepper flakes to the cheese sauce.
Make-Ahead Option: You can prepare the cauliflower and cheese sauce separately ahead of time. Store them in the refrigerator, and when ready to serve, combine them and broil as directed. This is great for easy weeknight dinners.

Serving & Storage Suggestions

Serve this Spicy Keto Cauliflower Mac N’ Cheese hot, straight from the broiler, for the ultimate cheesy experience. The toasted almonds and fresh chives add a lovely visual appeal and a burst of fresh flavor.

If you have any leftovers, store them in an airtight container in the refrigerator. They will keep for up to 3 days.

To reheat, you can microwave individual portions or bake the entire dish in a preheated oven at 350°F (175°C) until heated through. The microwave might make the cauliflower a bit softer, but it’s a quick and easy option. For a crispier top, broil it for a minute or two after reheating.
