Ingredients
Vegetables
- 1 medium sweet potato, peeled and diced
- 1 medium cauliflower, chopped
- 1 red bell pepper, chopped
- 1 small yellow onion, chopped
Other Ingredients
- 1 tablespoon oil
- 1/2 teaspoon salt
- 1 cup milk of choice
- 2 teaspoons garlic powder
- 2 teaspoons Dijon mustard
- 2 teaspoons cornstarch or arrowroot starch
- 2 cups shredded cheddar cheese
- 16 ounces elbow macaroni pasta
Instructions
- Roast the Vegetables: Preheat your oven to 400°F (200°C). Toss the diced sweet potato, chopped cauliflower, onion, and red bell pepper with oil and salt. Spread the vegetables evenly on a baking sheet and roast for 30-35 minutes until they are tender and slightly caramelized.
- Cook the Pasta: While the vegetables are roasting, bring a large pot of salted water to a boil. Cook the elbow macaroni according to the package directions until al dente. Reserve 1 cup of the pasta cooking water, then drain the pasta and set aside.
- Blend the Sauce: Transfer the roasted vegetables into a blender. Add the Dijon mustard, garlic powder, cornstarch, milk, and shredded cheddar cheese. Blend everything together until the mixture is smooth and creamy.
- Heat the Sauce: Pour the blended sauce into the same pot used for cooking the pasta. Warm the sauce over medium-low heat, stirring frequently to prevent sticking and to ensure even warming.
- Combine: Add the cooked macaroni into the sauce and toss thoroughly to coat each piece. Gradually add reserved pasta water a little at a time to adjust the sauce to your preferred consistency. Taste and season with additional salt and freshly ground black pepper as desired. Serve warm.
Notes
- Use Dijon mustard to add depth and a subtle tang to the cheese sauce.
- The reserved pasta water helps thin the sauce and aids in binding it to the pasta.
- You can substitute milk with any plant-based option for a dairy-free version.
- Feel free to add extra seasoning such as black pepper or paprika for extra flavor.
- Ensure vegetables are fully roasted to enhance natural sweetness and flavor.
