Ingredients
- 1 lb Elbow Macaroni or Shell Pasta
- 4 tablespoons Unsalted Butter
- 1/4 cup All-Purpose Flour
- 3 cups Whole Milk, warmed
- 8 oz Sharp Orange Cheddar Cheese, freshly shredded
- 4 oz Monterey Jack or Gruyère Cheese, freshly shredded
- 1/2 teaspoon Mustard Powder
- 1/2 teaspoon Smoked Paprika
- Salt and Black Pepper, to taste
- Green Gel Food Coloring
- For Monster Eyes: Sliced black olives or candy eyeballs
Step-by-Step Instructions
- Cook the Pasta: Cook the pasta according to package directions until al dente. Drain and set aside.
- Make the Roux: While the pasta is cooking, melt the butter in a large pot or Dutch oven over medium heat. Whisk in the flour and cook for 1 minute, stirring constantly, until it forms a smooth paste.
- Build the Sauce: Gradually whisk in the warm milk, a little at a time, until the sauce is completely smooth. Bring to a simmer, stirring frequently, until it has thickened enough to coat the back of a spoon (about 5-7 minutes).
- Melt the Cheese: Reduce the heat to low. Gradually stir in the shredded cheddar and Monterey Jack cheeses until completely melted and the sauce is smooth. Stir in the mustard powder, paprika, salt, and pepper.
- Make it Green: Add a few drops of green gel food coloring and stir until you reach a spooky, vibrant monster-green color.
- Combine and Serve: Add the cooked pasta to the cheese sauce and stir until everything is well-coated. Serve immediately in bowls, decorated with sliced black olives to look like monster eyes.
Tips & Variations
- Pro Tip: For the absolute creamiest, smoothest sauce, shred your own cheese from a block. Pre-shredded cheese is coated in starches that can make the sauce grainy.
- Baked Mac and Cheese: For a crispy topping, transfer the finished mac and cheese to a baking dish, top with buttered panko breadcrumbs, and bake at 375°F (190°C) for 15-20 minutes until golden and bubbly.
- Monster Add-ins: Stir in some sliced hot dogs or cooked ground beef to make it a “monster guts” mac and cheese.
- Different Colors: Use black food coloring (made from squid ink or activated charcoal) for a spooky “cauldron” mac and cheese, or use orange for a pumpkin theme.

Frequently Asked Questions (FAQ)
- How do I prevent my cheese sauce from becoming grainy?
- The key is to use freshly shredded cheese and to keep the heat on low once you start adding the cheese. This gentle melting prevents the cheese from separating.
- Can I make this ahead of time?
- You can make the cheese sauce a day in advance and store it in the refrigerator. Reheat it gently on the stovetop, adding a splash of milk to thin it out, before stirring in the freshly cooked pasta.
- How do I store leftovers?
- Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or on the stovetop with a splash of milk to restore its creaminess.
Serving Suggestions
- Serve this Monster Mac and Cheese hot, right from the pot. For a party, serve it from a large black bowl or a cauldron for extra spooky effect. It’s a fantastic main course on its own or a great side dish for a Halloween potluck.
