Ingredients

For this One Pot Veggie Mac and Cheese, you’ll need:

• 16 oz (450g) elbow macaroni or short pasta of choice
• 4 cups (950ml) vegetable broth
• 1 cup (240ml) whole milk
• 2 tablespoons (30g) unsalted butter
• 1 medium yellow onion, finely diced (about 1 cup)
• 2 cloves garlic, minced
• 1 medium red bell pepper, diced (about 1 cup)
• 2 cups (200g) broccoli florets, cut into small pieces
• 1 cup (150g) frozen peas
• 2½ cups (300g) shredded cheese blend (sharp cheddar, Monterey Jack, and Gruyère work well)
• ¼ cup (25g) grated Parmesan cheese
• ½ teaspoon mustard powder
• ¼ teaspoon cayenne pepper (optional)
• Salt and freshly ground black pepper to taste
• 2 tablespoons fresh parsley, chopped (for garnish)

The quality of cheese significantly impacts the final flavor of your cheesy vegetable pasta. Use freshly grated cheese rather than pre-shredded varieties, which contain anti-caking agents that can prevent smooth melting.

Pro Tips

Choose the Right Pasta: For the perfect One Pot Veggie Mac and Cheese, select pasta shapes with nooks and crannies that trap the creamy sauce. Medium shells, cavatappi, or traditional elbow macaroni work beautifully. Avoid long pasta shapes like spaghetti or linguine, as they won’t cook evenly in this one-pot method.

Master the One-Pot Technique: The key to success lies in frequent stirring, especially during the first 5 minutes of cooking. This prevents pasta from sticking to the bottom of the pot and ensures even cooking. Keep the heat at a gentle simmer rather than a rolling boil—this allows the pasta to absorb the liquid gradually while releasing its starches to naturally thicken the sauce.

Perfect Cheese Integration: For the silkiest sauce in your vegetable mac and cheese, remove the pot from heat before adding cheese and stir in handfuls gradually. The residual heat will melt the cheese without risking the sauce breaking or becoming grainy. If your sauce seems too thick after adding cheese, loosen it with a splash of warm milk, adding just a tablespoon at a time until reaching your desired consistency.

Instructions

Step 1: Prepare your mise en place by chopping all vegetables and measuring out your ingredients. This ensures the cooking process flows smoothly once you begin. Heat a large Dutch oven or heavy-bottomed pot over medium heat. Add butter and allow it to melt completely.

Step 2: Add the diced onions to the melted butter and sauté for 3-4 minutes until they become translucent and soft. Add the minced garlic and cook for another 30 seconds until fragrant, being careful not to let it brown or burn.

Step 3: Add the diced red bell pepper and broccoli florets to the pot. Sauté for another 2-3 minutes until the vegetables begin to soften slightly but still maintain some firmness. They’ll continue cooking with the pasta.

Step 4: Pour in the vegetable broth and milk, then add the mustard powder, cayenne pepper (if using), and a generous pinch of salt and black pepper. Bring the liquid to a gentle boil, stirring occasionally.

Step 5: Add the dry pasta to the pot and stir well to ensure it’s submerged in the liquid. Reduce heat to medium-low to maintain a steady simmer. Cook uncovered for about 8-10 minutes, stirring frequently to prevent sticking and promote even cooking. The pasta will absorb the liquid as it cooks.

Step 6: When the pasta is almost tender but still has a slight bite (about 2 minutes before it’s fully cooked), add the frozen peas and stir to combine. Continue cooking until the pasta reaches al dente texture and most of the liquid has been absorbed or reduced into a creamy sauce.

Step 7: Remove the pot from heat and immediately add the shredded cheese blend and Parmesan, a handful at a time, stirring constantly until each addition is fully melted and incorporated. This creates the silky, smooth cheese sauce that makes this One Pot Veggie Mac and Cheese so irresistible.

Step 8: Taste and adjust seasonings as needed. If the sauce seems too thick, add a splash of milk to reach your desired consistency. If too thin, let it sit for a couple of minutes to thicken naturally. Serve immediately, garnished with fresh parsley for a pop of color and fresh flavor.

Variations

Mediterranean Veggie Mac and Cheese: Transform your One Pot Veggie Mac and Cheese with Mediterranean flavors by replacing the bell pepper and broccoli with 1 cup halved cherry tomatoes, ½ cup chopped artichoke hearts, and ½ cup diced zucchini. Add 2 tablespoons of chopped Kalamata olives and ¼ cup crumbled feta cheese along with the cheddar. Finish with fresh basil instead of parsley and a drizzle of olive oil for an aromatic twist on this cheese pasta with vegetables.

Protein-Packed Mac and Cheese: For a heartier version, add 2 cups of protein to your vegetable mac and cheese. Try 2 cups of cooked shredded rotisserie chicken folded in after the cheese melts, or 1 can of drained and rinsed white beans added with the peas. For a plant-based option, stir in 1 cup of cooked quinoa and ½ cup of toasted walnuts for texture contrast and protein boost.

Dairy-Free Option: Create a vegan version by replacing the butter with olive oil, using plant-based milk, and substituting the cheese with 1 cup of soaked and pureed cashews blended with ¼ cup nutritional yeast, 1 tablespoon lemon juice, and ½ teaspoon garlic powder. This alternative still delivers creamy comfort while accommodating dairy restrictions.

Storage and Serving

This One Pot Veggie Mac and Cheese can be stored in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of milk before microwaving in 30-second intervals, stirring between each until heated through. This prevents the pasta from drying out and helps restore the creamy texture. For freezing, portion into individual containers and freeze for up to 1 month. Thaw overnight in the refrigerator before reheating.

Serve this cheesy vegetable pasta as a satisfying main dish in wide, shallow bowls that showcase the colorful vegetables. For a complete meal, pair it with a crisp side salad dressed with a light vinaigrette to balance the richness of the cheese sauce. For an elevated presentation, top each serving with toasted panko breadcrumbs mixed with a little melted butter and extra Parmesan for a crunchy contrast to the creamy pasta.

For a fun family dinner, set up a topping bar with crispy bacon bits, additional steamed vegetables, herbs, hot sauce, and extra cheese, allowing everyone to customize their bowl of comfort.

FAQs

Can I use gluten-free pasta in this One Pot Veggie Mac and Cheese?
Yes, gluten-free pasta works well, but you’ll need to adjust cooking times. Most gluten-free pastas cook faster than traditional wheat pasta, so check doneness about 2 minutes earlier. The liquid might need slight adjustment as well—start with about ¾ of the liquid called for and add more as needed.

Why did my cheese sauce turn grainy?
Grainy sauce usually happens when cheese is added to a mixture that’s too hot or when pre-shredded cheese (which contains anti-caking agents) is used. Always remove the pot from heat before adding cheese and use freshly grated cheese for the smoothest results.

Can I make this ahead of time for a potluck?
Yes, but make it slightly underdone initially, as it will continue cooking when reheated. Store with a little extra milk stirred in, and reheat gently on the stovetop with additional milk to refresh the sauce before serving.

What vegetables work best in this recipe?
Vegetables that can withstand some cooking time work best: broccoli, cauliflower, bell peppers, peas, carrots, and zucchini. Delicate vegetables like spinach should be stirred in at the very end to prevent overcooking.

My sauce is too thin. How can I thicken it?
If your sauce is too thin, continue simmering uncovered for a few extra minutes. The starch from the pasta will help thicken the sauce naturally. Alternatively, you can add an extra handful of cheese to help reach the desired consistency.
