Step 1: Cook the pasta
Bring a large pot of salted water to a boil, then cook the macaroni until just al dente. Drain it well and set it aside.
Step 2: Make the sauce base
In a large saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 to 2 minutes until it looks smooth and lightly bubbly.
Step 3: Add the milk
Slowly pour in the milk, whisking constantly so the mixture stays smooth. Cook for a few minutes until it thickens enough to coat the back of a spoon.
Step 4: Make it green and cheesy

Tips for Success
Cook the pasta just until al dente so it does not turn soft in the sauce. Blend the spinach very smoothly, so the sauce stays silky instead of flecked. If the sauce feels too thick, add a splash of milk before serving.
Variations of Monster Mac and Cheese
For a brighter flavor, blend in a little parsley or basil with the spinach. If you want more richness, add a spoonful of cream cheese. You can also top the finished dish with toasted breadcrumbs for extra crunch.
Serving Suggestions: What to Pair with Monster Mac and Cheese
This dish pairs nicely with a simple green salad, roasted broccoli, or steamed peas. It also works well alongside grilled chicken, baked meatballs, or a crisp apple slaw for a fun family dinner.
Storage & Reheating Instructions
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop or in the microwave with a splash of milk to bring back the creamy texture. If you plan to bake it later, keep the sauce and pasta slightly separate for the best texture.
