- Salt (½ teaspoon plus more to taste): Essential to bring out all the flavors and balance the creaminess.
- Pepper (¼ teaspoon plus more to taste): Adds just the right hint of spice to elevate the cheese sauce.

How to Make Baked Cauliflower Mac and Cheese Recipe
Step 1: Preheat Your Oven and Prepare Cauliflower
Start by preheating your oven to 350°F. While the oven warms up, chop your cauliflower into bite-sized florets. Cooking the cauliflower until tender is crucial; it should be soft enough to easily mash with a fork but still hold its shape once baked.
Step 2: Cook the Cauliflower
Place the cauliflower florets in a large pot, cover them with water, and bring to a boil. Lower the heat to medium-low and simmer for about 10-12 minutes until the cauliflower is tender but not mushy. Then drain well and set aside to avoid sogginess in your final dish.
Step 3: Sauté Onions to Build Flavor
While your cauliflower is cooking, warm the oil in a large saucepan over medium heat. Add the chopped onion and sauté for 3-4 minutes until they become soft and fragrant. This step adds a lovely natural sweetness that contrasts beautifully with the sharp cheddar cheese.
Step 4: Create the Cheese Sauce Base
Sprinkle in the arrowroot powder, salt, and pepper, stirring continuously with your onions for about 3-4 minutes. This cooks out the starchy taste of the arrowroot and starts thickening the base gently.
Step 5: Whisk in Almond Milk and Bring to a Boil
Slowly pour the unsweetened almond milk into your saucepan, whisking constantly to prevent lumps. Bring the mixture to a boil while whisking until it becomes smooth and thick. This will be the beautifully creamy base for your cheese sauce.
Step 6: Melt in the Sharp Cheddar Cheese
Remove your saucepan from heat and gradually add shredded cheddar cheese, whisking after each addition until the cheese is fully melted. You’ll have a rich, thick, and velvety sauce that clings perfectly to your cauliflower.
Step 7: Combine Cauliflower and Cheese Sauce
Fold your tender cauliflower florets into the cheese sauce, making sure every piece is well coated. This mix is what transforms simple veggies into the star of the show in this Baked Cauliflower Mac and Cheese Recipe.
Step 8: Bake Until Bubbling and Golden
Transfer the cheesy cauliflower mixture into a 9×13 baking dish. Bake for 25-30 minutes until the sauce is bubbly and the top starts to brown. For an extra golden crust, broil for an additional 3-4 minutes. Keep an eye on it so it doesn’t burn!
Step 9: Let it Cool and Serve
Remove the dish from the oven and let it cool slightly before serving. This will help the sauce set a bit, so your portions hold beautifully on the plate without being too runny.

FAQs
Can I use regular milk instead of almond milk?
Absolutely! Regular dairy milk will work fine and will make the sauce even creamier. Just choose whole milk or 2% for the best richness.
Is arrowroot powder necessary, or can I substitute it?
Arrowroot powder helps thicken the sauce smoothly, but cornstarch works just as well as a substitute in this recipe.
Can I add other cheeses to the recipe?
You can certainly mix it up! Adding mozzarella, gouda, or Monterey Jack will create different flavor profiles and textures, making it even more delicious.
How can I make this recipe vegan?
Swap the cheddar cheese for a vegan cheese alternative and make sure to use a plant-based milk. Nutritional yeast can also add a cheesy flavor boost.
Can this recipe be made gluten-free?
Yes! Using arrowroot powder or cornstarch as the thickener makes this recipe naturally gluten-free and safe for those with gluten sensitivities.
