- 1 tsp (5ml) Dijon mustard
- 1/2 tsp (2.5g) onion powder
- 1/4 tsp (1.2g) garlic powder
- 1/4 tsp (1.2g) freshly cracked black pepper
- 1/2 tsp (2.5g) fine sea salt
- 4 cups (450g) sharp cheddar cheese, freshly shredded
- 1 cup (115g) Gruyère cheese, freshly shredded (optional)
- For the Stuffed Peppers:
- 4 large bell peppers (any color), halved lengthwise, seeds removed
- 1 tbsp (15ml) olive oil
- Salt and freshly ground black pepper
- Optional Crispy Topping and Garnish:
- 1/2 cup (60g) panko breadcrumbs
- 2 tbsp (30g) unsalted butter, melted
- 1/4 cup (30g) extra sharp cheddar cheese, freshly shredded
- 2 tbsp (30g) fresh parsley, chopped
Instructions
- Bring a large pot of water to a rolling boil. Add elbow macaroni. Cook 7-9 minutes until al dente. Drain well; set aside.
- Preheat oven to 375°F (190°C). Grease a 9×13 inch (23×33 cm) baking dish. Arrange halved bell peppers, cut-side up, in a single layer. Drizzle with 1 tbsp (15ml) olive oil. Season with salt and pepper.
- Melt 1/4 cup (55g) unsalted butter in a large saucepan over medium heat. Add 1/4 cup (30g) all-purpose flour. Whisk constantly for 1-2 minutes until a smooth, pale golden roux forms.
- Gradually whisk in 3 cups (720ml) warmed whole milk. Whisk over medium heat for 3-5 minutes until sauce thickens and coats the back of a spoon.
- Stir in 1 tsp (5ml) Dijon mustard, 1/2 tsp (2.5g) onion powder, 1/4 tsp (1.2g) garlic powder, 1/4 tsp (1.2g) ground black pepper, and 1/2 tsp (2.5g) fine sea salt. Cook 1 minute.
- Remove saucepan from heat. Add 4 cups (450g) freshly shredded sharp cheddar cheese and 1 cup (115g) freshly shredded Gruyère cheese (optional). Stir until cheese is completely melted and sauce is smooth.
- Add cooked elbow macaroni to cheese sauce. Stir until pasta is evenly coated.
- Spoon mac and cheese mixture into each bell pepper half.
- In a small bowl, combine 1/2 cup (60g) panko breadcrumbs and 2 tbsp (30g) melted unsalted butter. Toss to coat. Sprinkle breadcrumbs over mac and cheese in stuffed peppers. Top with 1/4 cup (30g) freshly shredded extra sharp cheddar cheese.
- Bake for 25-30 minutes, until peppers are tender-crisp, mac and cheese filling bubbles, and topping is golden brown and crispy.
- Remove baking dish from oven. Rest 5 minutes. Garnish with 2 tbsp (30g) fresh chopped parsley (optional). Serve warm.
Notes
- For heat, add 1/4 tsp (1.2g) cayenne pepper to the cheese sauce in step 5.
- Prepare mac and cheese and stuff peppers. Cover baking dish with foil; refrigerate up to 24 hours. When baking from cold, add 10-15 minutes to bake time. Ensure internal temperature reaches 165°F (74°C).
- Substitute other melting cheeses for cheddar and Gruyère, such as smoked gouda, Monterey Jack, or sharp provolone.
- Warm milk before adding to roux.
Pro Tips for Perfect Mac And Cheese Stuffed Peppers
Ingredient Tips
- Bell Pepper Pre-Bake:Pre-bake 3 large (8-10 oz) bell peppers, halved and seeded, face-down at 400°F (200°C) for 15 minutes. This ensures fork-tender peppers, avoiding a raw crunch in the final dish.
- Al Dente Macaroni Prep:Cook 8 oz elbow macaroni 2 minutes less than package directions (e.g., 6 min). Drain thoroughly, then return to the hot pot off heat for 1 minute to evaporate clinging water, preventing mushiness.
- Freshly Shredded Cheese Blend:For optimal melt and flavor, combine 8 oz sharp cheddar and 4 oz Gruyère, freshly shredded from a block. Pre-shredded cheese causes grainy sauce due to anti-caking agents; fresh yields a silky-smooth sauce.
- Whole Milk for Richness:Use 2 cups whole milk (3.25% fat) in your béchamel. Higher fat prevents the cheese sauce from breaking or becoming watery during the 20-25 minute oven bake.
Technique Tips
- De-Watering Peppers:After halving and seeding the 3 bell peppers, sprinkle the cut insides of each (6 halves total) with 1/4 teaspoon kosher salt. Rest them cut-side down on paper towels for 15 minutes to draw out excess moisture. Pat bone-dry before pre-baking, preventing sogginess.
- Perfect Roux Execution:Melt 4 tbsp unsalted butter; whisk in 4 tbsp all-purpose flour. Cook this roux over medium-low heat for 2 minutes, stirring constantly. Forms a pale, nutty-smelling paste, ensuring no raw flour taste.
- Gradual Off-Heat Cheese Addition:Once béchamel thickens, remove it from heat. Add shredded cheese 1/2 cup at a time, whisking continuously until fully melted and smooth. Prevents clumping, yielding velvety sauce that slides off a spoon.
- Optimal Stuffing Level:Fill each pre-baked pepper half, mounding slightly, but ensuring a 1/4-inch clearance from the top rim. Overfilling causes excessive cheese overflow and potential burning during the 20-25 minute bake at 375°F (190°C).
- Crisp Toasted Panko Timing:Toast 1/2 cup Panko with 2 tbsp melted butter and 1/4 tsp garlic powder for 3-5 minutes until golden brown. Sprinkle this topping on peppers only during the last 10 minutes of 375°F (190°C) baking for crispness, preventing burns.
Common Issues
- Stiff/Dry Mac & Cheese:Overbaking or insufficient sauce causes this. Ensure 2.5 cups of cheese sauce for 8 oz pasta. Reduce 375°F (190°C) baking by 5-7 minutes, removing when edges bubble vigorously (165°F / 74°C internal).
- Gritty/Separated Cheese Sauce:Pre-shredded cheese or overheating causes this. Always shred 8 oz cheddar and 4 oz Gruyère yourself. Add cheese off heat, 1/2 cup at time, whisking until smooth, coating a spoon.
- Peppers Remain Too Firm:If not fork-tender after the main bake, increase initial pre-bake to 20-25 minutes at 400°F (200°C). Alternatively, cover stuffed peppers loosely with foil for the first 15 minutes of the 375°F (190°C) final bake.
- Burnt Panko Topping:Burnt 1/2 cup Panko means it was added too early. Add pre-toasted, buttered Panko only during the last 8-10 minutes of 375°F (190°C) baking, or tent with foil for initial 15 minutes.
Storage, Reheating, and Flavor Variations
Proper storage and reheating ensure Mac and Cheese Stuffed Peppers remain a delightful comfort food, perfect for leftovers or meal prep, maintaining optimal flavor and texture.
Refrigerator Storage
Duration: 5-7 days in an airtight container
Store cooled peppers in an airtight glass container or food-safe plastic container. Glass prevents odor absorption and maintains pepper integrity. Over time, peppers soften, and the mac and cheese sauce may thicken or dry out, especially at the edges. While safe, mac and cheese can firm, and the dish loses some “freshly baked” brightness after day 5. For best quality, consume within 3-4 days.
Freezer Storage
Duration: 2-3 months
Cool cooked peppers completely before freezing. Wrap each pepper tightly in plastic wrap, then place in a freezer-safe heavy-duty freezer bag or an airtight container. For multiple peppers in a dish, wrap the entire dish tightly with plastic wrap and foil. Thaw frozen peppers overnight (8-12 hours) in the refrigerator. Expect texture changes: bell peppers become significantly softer, potentially mushy. Mac and cheese sauce may show slight separation (grainy/oily) but often re-emulsifies during reheating. The cheese topping might also lose crispness.
Reheating Instructions
- Oven (Best Method):Preheat oven to 350°F (175°C). Place refrigerated peppers in an oven-safe dish, cover loosely with foil, and bake for 15-20 minutes, until heated through and cheese bubbles. For thawed frozen peppers, bake 25-30 minutes. Remove foil for the last 5 minutes for a crispy topping. This method ensures even heating and restores texture.
- Microwave (Acceptable, with caveats):Place a single pepper on a microwave-safe plate, cover loosely with a damp paper towel. Heat on medium-high power for 1.5-3 minutes, rotating halfway, until hot. Microwaving can make bell peppers rubbery or mushy; mac and cheese may become chewy on edges and drier in the center. Sauce separation can be more noticeable.
- Air Fryer (Good for Crispiness):Place refrigerated peppers in a single layer in the air fryer basket. Cook at 325°F (160°C) for 8-12 minutes, checking halfway, until heated through and the cheese topping is re-crisped. For thawed frozen, add 5-7 minutes. This method excels at re-crisping the topping but can dry out the mac and cheese if overcooked.
Make-Ahead Tips
Prepare components in advance. The mac and cheese filling can be made up to 3 days ahead, stored in an airtight container in the refrigerator. Par-bake bell peppers (roast at 375°F for 15-20 minutes until slightly tender) up to 2 days in advance, then cool and store in a sealed bag or container in the fridge. For maximum convenience, assemble the entire dish (stuff peppers) up to 24 hours before baking. Place assembled uncooked peppers in a baking dish, cover tightly with plastic wrap, and refrigerate. Before baking, remove from the fridge 30 minutes prior to reach room temperature, then bake as directed, adding 5-10 minutes if chilled.
