How to Make Veggie Mac

Start by heating olive oil in a large saucepan or 12-inch skillet over medium-high heat. Sauté the diced onions until soft, about 3 minutes, then stir in the garlic and cook for another minute until fragrant.
Next, pour in 1/2 cup of the vegetable broth and sprinkle in the flour. Stir until a paste forms. This is the start of your cheesy sauce! Let it cook for a minute or two to get rid of any floury taste.
Then, slowly stir in the remaining broth and milk. Add the elbow macaroni and vegetables, and bring everything to a low simmer. Reduce the heat to low-medium heat and cook uncovered, stirring frequently, for about 10 minutes or until the pasta is al dente.
Remove from the heat and stir in the cheddar cheese until it’s fully melted and the sauce is creamy. If the sauce thickens too much, add a splash of milk to loosen it up. Season with black pepper or garlic powder if desired.
Serve hot, straight from the pot, or transfer to a baking dish, sprinkle with bread crumbs and bake until golden brown for a baked twist!

Expert Tips and Substitutions

Fresh or frozen veggies work great – Frozen mixed vegetables make this dish easy, but feel free to use chopped fresh bell peppers, cherry tomatoes, or even sweet potatoes.
Add spice – Stir in a pinch of cayenne pepper, red pepper flakes, or a dash of hot sauce for extra flavor.
Try a cheesy upgrade – Mix in a little dijon mustard or nutritional yeast for a sharper cheese flavor.
Swap the pasta – Whole grain or bean pasta adds extra nutrition and fiber.
Blend the sauce – Use an immersion blender before adding the cheese for a super smooth sauce (especially helpful for hidden veggie mac!).

Storing and Making Ahead

Store leftovers in an airtight container in the fridge for up to 2 days. Reheat gently over low heat on the stovetop, adding a splash of milk to bring back the creamy texture.

This dish can also be made ahead and stored in a baking dish. Top with breadcrumbs and refrigerate until ready to bake at 375°F until hot and golden brown.
