Why You’ll Love Monster Mac and Cheese
Creamy cheesy and full of flavor Naturally green from spinach with no food coloring Perfect for kid’s adults and spooky Halloween nights Freezer-friendly sauce for future meals Just a handful of simple ingredients.
Ingredients
1 head of cauliflower or 4 cups frozen cauliflower
1 pound small pasta like macaroni or shells
2 cups baby spinach
1 cup milk whole skim or oat
1 and a half cups shredded cheddar cheese
1 teaspoon kosher salt
One fourth teaspoon ground black pepper optional
How to Make Monster Mac and Cheese
Cut the cauliflower into large pieces and place in a large pot with enough water to cover. Bring to a boil then reduce the heat and simmer for 5 to 8 minutes until the cauliflower is fork-tender.
While the cauliflower cooks prepare the pasta according to package directions. Before draining save 1 cup of the pasta water to adjust the sauce later if needed.
Add the cooked cauliflower baby spinach milk cheese salt and pepper to a blender or food processor. Blend for 1 to 2 minutes until the sauce is creamy and smooth. If the sauce is too thick add a bit of pasta water one fourth cup at a time until it reaches your desired consistency.
Mix the green sauce with the cooked pasta. Use the full amount for an ultra-creamy mac or half the sauce for a firmer boxed-style texture. Add more salt or pepper to taste if needed.
What Makes It Green
The vibrant green color comes entirely from fresh baby spinach. No food coloring required. Spinach has a mild flavor that blends easily with cauliflower and cheese creating a smooth veggie-loaded sauce that looks fun but tastes familiar. Other leafy greens like kale or chard can also be used though they may have a stronger flavor.
Substitutions and Variations
Cheese
Use white cheddar to keep the green color bright or swap in gruyere gouda or Monterey jack for different flavor profiles
Greens

Tips for Success
