Vegetarian Chili Mac Ingredients
For the Base
- Olive Oil – Provides healthy fat for sautéing; substitute with avocado oil for higher smoke point.
- Chopped Onion – Base for flavor; adds sweetness when cooked, and can be replaced with shallots for a milder taste.
- Bell Pepper – Adds color and crunch; any color works, or swap with zucchini for a lower-carb option.
- Carrots – Acts as a natural sweetness enhancer; use diced sweet potato for added texture if desired.
- Garlic – Enhances flavor; fresh garlic is best, but garlic powder works in a pinch.
For the Chili Flavor
- Chili Powder – Adds warmth and depth; adjust to taste, or try taco seasoning for a different profile.
- Ground Cumin – Provides earthiness; essential for chili flavor—omit if unavailable but expect less depth.
- Salt – Enhances overall flavor; adjust according to dietary needs, or replace with a salt substitute for low-sodium diets.
For the Sauce and Pasta
- Canned Diced Tomatoes – Provides acidity and moisture; essential for the sauce, and you can swap with crushed tomatoes.
- Canned Diced Tomatoes with Green Chilies – Adds extra spiciness; adjust to your preferred heat level, or use mild variants.
- Elbow Macaroni Pasta – Forms the base of the dish; both whole wheat and regular work, or substitute with gluten-free pasta.
For the Protein and Creaminess
- Black Beans – Source of protein and fiber; can substitute with lentils for a different texture.
- Red Kidney Beans – Adds bulk and nutrition; rinse before use, or try pinto beans for variety.
- Water – Helps cook the pasta and creates the sauce; for more flavor, use vegetable broth instead.
- Shredded Cheese – Adds creaminess; mix different types like cheddar or Monterey Jack, or use plant-based cheese for a vegan option.
Step‑by‑Step Instructions for Vegetarian Chili Mac
Step 1: Sauté the Vegetables
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Once hot, add the chopped onion, bell pepper, and carrots, stirring frequently for about 6 minutes until the vegetables are tender and slightly caramelized, adding sweetness to your Vegetarian Chili Mac.
Step 2: Add Aromatics and Spices
Next, stir in 3 cloves of minced garlic along with 2 tablespoons of chili powder, 1 teaspoon of ground cumin, and 1 teaspoon of salt. Cook the mixture for approximately 30 seconds until fragrant, allowing the spices to bloom and enhance the flavor profile of your chili.
Step 3: Combine with Saucy Ingredients
Pour in a 14-ounce can of diced tomatoes, a 10-ounce can of diced tomatoes with green chilies, 1 cup of elbow macaroni, 1 can each of black beans and red kidney beans (drained and rinsed), and 2 cups of water. Stir everything together to ensure an even mix before preparing to bring it to a boil.
Step 4: Simmer the Chili Mac
Increase the heat to medium-high, bringing the mixture to a gentle simmer. Once bubbling, reduce the heat to low, cover the skillet, and cook for 12-15 minutes. Stir occasionally until the pasta is tender and most of the liquid is absorbed, resulting in a thick, hearty texture.
Step 5: Add Cheese and Serve
Remove the skillet from heat and stir in 1 cup of shredded cheese, allowing it to melt into the chili mac. Sprinkle the remaining cheese on top for an irresistible finish. Serve hot and enjoy this comforting, delicious Vegetarian Chili Mac at your family dinner.

Vegetarian Chili Mac Recipe FAQs
What type of tomatoes should I use for the best flavor?
Absolutely! For a robust flavor, I recommend using a combination of canned diced tomatoes and diced tomatoes with green chilies. The latter adds a touch of heat and extra spice. If you prefer a milder dish, simply opt for regular diced tomatoes or crushed tomatoes instead.
How can I store leftover Vegetarian Chili Mac?
To keep your Vegetarian Chili Mac fresh, let it cool for about 30 minutes at room temperature before transferring it to an airtight container. You can store it in the refrigerator for up to 3 days. If you want to prolong its life, freeze it in an airtight container for up to 3 months. Make sure to thaw overnight in the refrigerator when you’re ready to reheat it!
Can I freeze Vegetarian Chili Mac? What is the best way to do it?
Very! To freeze your Vegetarian Chili Mac, allow it to cool completely, then portion it into airtight containers or freezer bags—this helps with quicker thawing. Make sure to remove as much air as possible to prevent freezer burn. When you’re ready to enjoy it, simply thaw overnight in the fridge and reheat in the microwave or stovetop until warm.
What should I do if my Chili Mac turns out too watery?
Don’t worry, it happens! If your Chili Mac is a bit runny, you can simply simmer it uncovered on low heat for a few extra minutes to let some of the liquid evaporate and thicken the sauce. You can also add a little instant pasta or cornflour mix (1 tablespoon per cup of liquid) to help absorb the excess moisture and get that creamy texture you desire.
Is there a way to make this dish gluten-free?
Absolutely! For a gluten-free version of my Vegetarian Chili Mac, just swap out the elbow macaroni pasta for gluten-free pasta, which is now widely available. Additionally, be sure to check any canned beans or tomatoes you use to ensure they don’t contain any gluten-containing additives.
Can I add meat to this recipe if I want?
Of course! If you’d like to add meat, brown some ground turkey or beef after sautéing your vegetables before adding the other ingredients. Just be mindful that this will increase the cooking time slightly, but it will add a hearty twist to this comforting dish.
