How to Make One Pot Veggie Mac and Cheese

Ingredients

8 oz (about 226 g) macaroni pasta (or your favorite small pasta)
2 cups (480 ml) vegetable broth
1 cup (240 ml) milk (2% or your choice)
1 cup (about 113 g) shredded cheddar cheese (or blend of cheddar + fontina)
1 cup mixed vegetables (fresh or frozen; e.g., broccoli florets, peas, carrots)
1 tablespoon olive oil
Salt and freshly ground black pepper, to taste

Optional ingredients and substitutions:

Swap milk for unsweetened plant milk (oat or soy) for a lighter or dairy-free base (see vegan variation below).
Use low-sodium vegetable broth to control salt.
Substitute 1/2 cup Greek yogurt for part of the milk for tang and protein.
Try smoked cheddar or a mix of sharp and mozzarella for different cheese profiles.
Add a pinch of nutmeg or mustard powder to deepen flavor.

Method

Heat: In a large pot over medium heat, add the olive oil and warm for 30 seconds.
Sauté vegetables: Add the mixed vegetables and sauté 2–3 minutes until slightly tender and fragrant. If using frozen vegetables, sauté until thawed and any excess water evaporates.
Add pasta and liquids: Stir in the macaroni, then pour in the vegetable broth and milk. Give everything a gentle stir to combine.
Simmer: Bring the pot to a simmer over medium-high heat. Once simmering, reduce heat to medium-low and cook uncovered for 10–12 minutes, stirring occasionally to prevent sticking and to ensure even cooking. The pasta should be tender and most liquid absorbed.
Finish with cheese: Remove the pot from heat. Stir in the shredded cheese until melted and the sauce is creamy. If the mixture seems too thick, add a splash more milk or broth to loosen it.
Season and serve: Taste and adjust with salt and pepper. Serve immediately while warm.

Practical tips:

Stir every few minutes to prevent pasta from sticking to the bottom and to distribute the vegetables evenly.
Check doneness early — different pasta brands cook at different rates; start testing at 8 minutes.
If you prefer a silkier sauce, grate the cheese finely and add it off the heat to avoid graininess.
For a silkier, creamier finish, stir in a tablespoon of butter at the end.

Best Pairings

Simple greens: A crisp arugula or mixed greens salad with lemon vinaigrette cuts the richness.
Protein boost: Top with grilled chicken strips, roasted chickpeas, or crispy tofu for a heartier meal.
Comfort sides: Warm garlic bread, roasted Brussels sprouts, or a bowl of tomato soup make cozy companions.
Drinks: For casual dinners, a cold glass of iced tea or a light white wine (like Pinot Grigio) pairs nicely.

Storage Instructions

Room temperature: Not recommended to leave mac and cheese at room temperature for more than 2 hours. Bacteria multiply quickly at room temp, so refrigerate promptly.
Refrigeration: Store in an airtight container for 3–4 days. Reheat gently on the stove over low heat with a splash of milk to restore creaminess, or microwave in 30-second bursts, stirring between intervals.
Freezer: You can freeze portions in airtight containers for up to 2 months. Thaw overnight in the refrigerator before reheating. Note: texture may change slightly after freezing; add extra milk or broth while reheating to revive creaminess.

Chef’s Advice

Cheese choice matters: Use flavorful, melting cheeses like sharp cheddar, gruyère, fontina, or a mix. Avoid pre-shredded cheeses with anti-caking agents if you want the creamiest melt.
Control salt carefully: Vegetable broth and cheese both add sodium. Start with low-sodium broth and taste before adding salt.
Texture cues: Aim for pasta that’s just tender — overcooking will make the dish gluey. If the sauce is too thin, simmer a minute longer; if too thick, stir in a tablespoon of milk at a time.
Build flavor: A teaspoon of Dijon mustard, a pinch of smoked paprika, or a squeeze of lemon can brighten the final dish and create deeper flavor layers.

Creative Twists

Vegan version: Use unsweetened soy or oat milk, a vegan cheddar-style shredded cheese (or nutritional yeast + cashew cream), and omit olive oil or replace with vegan butter. Cook the same way using vegetable broth.
Gluten-free option: Swap macaroni for a gluten-free pasta and follow the same steps. Note that cooking times may vary and some gluten-free pastas can get softer quickly — check early.
Protein-packed: Stir in a can of drained white beans or pan-seared chicken breast slices after cooking for extra protein.
Spicy kick: Add a chopped jalapeño while sautéing vegetables or finish with a drizzle of hot honey or Sriracha.
Herby finish: Fold in chopped fresh chives, parsley, or basil just before serving for freshness.

Frequently Asked Questions
Q: Can I use whole milk or non-dairy milk?
A: Yes — whole milk will make the sauce richer; 2% is a good balance. Unsweetened non-dairy milk (soy or oat) works for dairy-free versions; if not using cheese, add nutritional yeast or vegan cheese for flavor.

Q: My sauce turned grainy after adding cheese. What went wrong?
A: Overheating cheese can cause it to separate and become grainy. Remove the pot from heat before stirring in cheese and add it gradually, stirring gently until just melted.

Q: Can I double the recipe for a crowd?
A: Yes. Use a larger pot and increase liquid proportionally. Stir frequently during cooking and allow extra simmering time as larger volumes may take longer to come to temperature.

Q: How can I make it lower in sodium?
A: Use low-sodium or homemade broth, choose low-salt cheese or reduce the cheese amount slightly, and skip added salt until after tasting.

Q: Is it freezer-friendly?
A: Yes — store in airtight containers for up to 2 months. Texture may change; add milk when reheating to refresh creaminess.
