Ingredients
- Large bell peppers: You want a variety of colors for visual appeal and a gentle sweet flavor Choose peppers that can stand upright and feel heavy for their size
- Elbow macaroni: Their small curved shape captures sauce for an ultra-creamy bite Opt for sturdy pasta that will hold up in baking
- Unsalted butter: Essential for a rich cheese sauce Look for high quality butter for best flavor
- All-purpose flour: This thickens the roux Ensure it is fresh and sifted for no lumps
- Whole milk: Gives a luxuriously creamy texture Use the full-fat variety for extra richness
- Salt and black pepper: These season the sauce and balance the sweetness of the peppers Kosher salt and freshly cracked pepper recommended
- Dijon mustard: Optional but adds tang and depth Choose a smooth strong Dijon
- Smoked paprika: Lends a subtle smokiness Opt for Spanish smoked paprika for best results
- Sharp cheddar cheese: Brings sharpness and classic mac and cheese flavor Shred your own for the best melting and taste
- Mozzarella cheese: Gives extra stretch and mild creaminess Use low-moisture whole milk mozzarella
- Grated Parmesan cheese: Sprinkled on top for a savory nutty finish Freshly grated tastes best
- Panko breadcrumbs: Add a light crunch Choose panko for crispier texture compared to regular breadcrumbs
- Olive oil: Ensures the topping bakes to golden perfection Choose extra virgin for the best taste
Instructions
- Prep the Peppers:
- Slice the tops off the peppers and carefully pull out seeds and white membranes Gently rinse the cavities Stand the peppers upright in a lightly greased baking dish They should fit snugly so they do not tip over
- Cook the Pasta:
- Bring a large pot of salted water to a rolling boil Stir in elbow macaroni and cook until just al dente Usually one to two minutes less than package instructions Drain pasta immediately and set aside so it does not overcook
- Make the Cheese Sauce:
- Melt butter over medium heat in a saucepan Once bubbling and frothy sprinkle in the flour and whisk constantly for a full minute This cooks out any raw flour taste and forms a roux
- Thicken the Sauce:
- Slowly pour in whole milk while whisking vigorously Continue to add salt black pepper Dijon mustard and smoked paprika Keep whisking until the mixture bubbles and thickens slightly This usually takes two to three minutes and you want the sauce to coat the back of a spoon
- Add Cheese:
- Take the pan off the heat and immediately fold in shredded cheddar and mozzarella Stir until completely melted and smooth The sauce will look glossy and thick
- Combine Pasta and Sauce:
- Fold your cooked pasta gently into the cheese sauce Make sure every piece is thoroughly coated with the sauce It should look creamy and luscious but not soupy
- Fill the Peppers:
- Spoon the mac and cheese mixture into each prepared pepper filling them to the very top of the cavity Press gently to ensure there are no air pockets
- Prepare the Topping:
- In a small bowl mix grated Parmesan cheese panko breadcrumbs and olive oil Toss together with a fork until breadcrumbs are evenly coated This gives your peppers a golden and crisp finish
- Bake Covered:
- Cover the dish with foil and bake in a 190 degree Celsius oven for 25 minutes This helps the peppers soften while the cheesy filling melds
- Finish Uncovered:
- Remove the foil and return the dish to the oven for ten minutes You are looking for a crispy bubbling golden crust and tender but still upright peppers
- Rest and Serve:
- Let the stuffed peppers cool for five minutes in the pan before serving This allows the cheese sauce to set and makes them easier to handle
