Ingredients of the Halloween Monster Mac and Cheese
For the Pasta

- 1 cup gruyere cheese, shredded
- 2 cups whole milk
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 1/2 cup pureed spinach (for green monster) or beet puree (for red monster)
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder

Equipment / Tools Needed
- Large pot for boiling pasta

Step-by-Step Instructions
Step 1: Prepare the Pasta
Bring a large pot of salted water to a boil. Add the pasta shells and cook until al dente, usually about one minute less than the package instructions suggest. Drain well and set aside, tossing with a little olive oil to prevent sticking.
Step 2: Create the Roux
In a medium saucepan over medium heat, melt the butter until it bubbles. Whisk in the flour and cook for about two minutes, ensuring the mixture smells nutty and turns a light golden color, which prevents a raw flour taste.
Step 3: Build the Sauce
Gradually pour in the milk while whisking constantly to avoid lumps. Continue stirring until the sauce thickens and coats the back of a spoon. Add the garlic powder and onion powder, then fold in your choice of spinach or beet puree to create your desired monster color.
Step 4: Melt the Cheese
Reduce the heat to low. Add the shredded cheddar and gruyere in handfuls, stirring slowly until the cheese is completely melted and the sauce is smooth, glossy, and vibrant. If the sauce feels too thick, splash in an extra tablespoon of milk.
Step 5: Assemble and Serve
Pour the cheese sauce over the cooked shells and stir gently until every piece is coated. Garnish with black olive slices arranged to look like eyes for that extra monster flair.
Tips & Tricks
Always grate your cheese fresh from the block. Pre-shredded cheese is coated in potato starch, which prevents it from melting into a perfectly smooth sauce. For the best flavor, keep the heat low while incorporating the cheese to avoid splitting the sauce.
Serving Suggestions
Serve this dish in shallow bowls to showcase the color. Pair it with a side of roasted carrots or a simple green salad to balance the richness of the pasta. It is an excellent main course for a festive October dinner party.
Variations / Substitutions
You can substitute the cheese varieties with fontina or monterey jack for different melting profiles. If you prefer to skip the vegetable purees, a small drop of natural food coloring can achieve the same aesthetic without altering the flavor profile.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to three days. To reheat, add a small splash of milk and warm over low heat on the stove, stirring frequently to bring back the creamy consistency.

FAQ
Can I make this dish ahead of time?
Yes, you can prepare the sauce and pasta separately. Combine them just before serving to ensure the best texture, as pasta tends to absorb the sauce if left sitting for too long.
How do I keep the sauce from becoming grainy?
The key is low heat. Never let the cheese sauce reach a boil once the cheese is added, as this will cause the proteins to seize and the oil to separate.
Can I use different vegetables for coloring?
Absolutely. Carrot puree provides a vibrant orange, while spinach is excellent for green. Ensure your purees are very smooth so they blend seamlessly into the sauce.
Is this recipe freezer-friendly?
Cream-based sauces can sometimes break when frozen and thawed. It is best to enjoy this dish fresh rather than freezing it for later use.
