This spooky Halloween Cheesy Broccoli Pasta Bake transforms ordinary pasta night into a festive celebration. The creamy cheese sauce envelops tender broccoli and al dente pasta, while fun olive "spiders" and bell pepper "jack-o'-lanterns" create a Halloween masterpiece that's as delicious as it is entertaining.
I first created this dish when my nieces and nephews were coming over for a pre Halloween dinner. The squeals of delight when they saw the olive spiders crawling across their pasta made this an instant tradition in our family gatherings.
Ingredients
- Short pasta penne fusilli or macaroni: forms the hearty base and captures the creamy sauce in every bite
- Broccoli florets: add nutrition and a pop of color that contrasts beautifully with the cheese
- Sharp cheddar cheese: provides rich flavor depth choose a good quality aged cheddar for best results
- Parmesan cheese: adds that umami note that makes the sauce irresistible look for authentic Parmigiano Reggiano
- Black olives and orange bell peppers: transform into spooky decorations select firm bell peppers with thick walls for best cutting results
- Panko breadcrumbs: create that perfect golden crunchy topping toast them lightly in butter beforehand for extra flavor
Instructions
- Prep the base:
- Boil your pasta until just shy of al dente about 2 minutes less than package directions. This undercooking is crucial as the pasta will continue to soften in the oven. Add the broccoli florets during the final 2 minutes this perfectly blanches them without turning mushy. The pasta and broccoli should both retain some firmness when you drain them.
- Create the cheese sauce:
- Start by melting butter in a large saucepan over medium heat until it foams slightly but doesn't brown. Add the diced onion and cook until translucent and softened about 2 minutes. The onions should become aromatic but not browned. Add garlic and cook for just 1 minute being careful not to burn it as this would create bitterness.
- Build the roux:
- Sprinkle the flour over the butter onion mixture and whisk continuously for a full minute. This cooking time eliminates the raw flour taste and creates the foundation for a smooth sauce. The mixture should look like wet sand and smell slightly nutty.
- Develop the sauce:
- Pour the milk in gradually about a quarter cup at a time whisking constantly to prevent lumps from forming. Continue whisking as the mixture comes to a gentle simmer. You'll notice it thickening around the 4 minute mark. The sauce should coat the back of a spoon when ready.
- Add the cheese:
- Remove the pan from heat before stirring in the cheddar Parmesan nutmeg salt and pepper. The residual heat will melt the cheese without risking separation. Stir until completely smooth and velvety. Taste and adjust seasonings remembering the cheese adds saltiness.
- Assemble and decorate:
- Fold the drained pasta and broccoli into the cheese sauce ensuring every piece is well coated. Transfer to your baking dish spreading evenly. Now comes the fun part creating your Halloween decorations. Cut olive halves into spider bodies and thin strips for legs. Arrange bell pepper pieces into jack o lantern faces smiling or spooky as you prefer.
- Bake to perfection:
- Sprinkle the top with mozzarella cheese and panko breadcrumbs for that irresistible golden crust. Bake uncovered until the edges bubble and the top turns golden brown about 20 to 25 minutes. Allow the pasta bake to rest for 5 minutes before serving this helps the sauce set slightly and prevents burning mouths.

The nutmeg in this recipe is my secret weapon. It might seem strange in a savory dish but it adds an almost magical warmth that complements the cheese perfectly. My grandmother always added it to her cheese sauces and now I cannot make one without thinking of her kitchen on chilly October evenings.
Make-Ahead Magic
For busy Halloween nights when trick or treating takes priority prepare this dish up to the baking point. Cover tightly and refrigerate for up to 24 hours. When ready to serve remove from the refrigerator 30 minutes before baking to take the chill off then bake as directed adding about 10 minutes to the cooking time. The decorations can be prepared ahead too just store them in water with a splash of lemon juice to prevent browning.
Dietary Adaptations
This versatile dish easily accommodates dietary restrictions without sacrificing flavor. For gluten free guests substitute your favorite gluten free pasta and a one to one gluten free flour blend for the roux. Dairy free versions work surprisingly well using plant based milk butter and cheese alternatives look for ones specifically formulated for melting. To boost the protein content for growing goblins fold in white beans chickpeas or even cooked ground turkey before baking.
Beyond Halloween
While designed as a Halloween treat this pasta bake transitions beautifully to other occasions. For Thanksgiving replace the spooky decorations with roasted butternut squash pieces. Christmas calls for red bell pepper stars and green broccoli trees. For everyday family meals skip the decorative elements and add extra vegetables like peas mushrooms or spinach. The cheese sauce base remains your constant companion through all seasonal variations.

Success Stories
Parents consistently tell me this dish has converted vegetable skeptics into broccoli enthusiasts. The cheese sauce works its magic making vegetables disappear faster than candy on Halloween night. One mom shared that her daughter requested this pasta bake for her birthday dinner complete with olive spiders even though it was months past Halloween. Another family created a tradition of making this dish while carving pumpkins turning meal prep into part of their Halloween festivities.
This dish is a guaranteed hit for spooky gatherings and family dinners alike. Enjoy creating your festive masterpiece!
