Ingredients & Equipment
Ingredients
- 1 lb. ground beef (85% lean)
- 2 1/2 cups elbow macaroni
- 14.5 oz can of diced tomatoes with green chilies
- 8 oz can tomato sauce
- 2 tablespoons chili powder
- 1/2 tablespoon cumin
- 1 teaspoon salt, divided
- 1 cup shredded colby jack cheese
- 3 1/2 cups water
Quick notes on ingredients
- Use 85% lean ground beef for good flavor with manageable fat; if you prefer leaner, expect a drier finish and consider reducing initial saute time.
- Diced tomatoes with green chilies add a bright, slightly smoky heat — swap for plain diced tomatoes plus a diced jalapeño if you want more control over spice.
- Colby jack melts beautifully; cheddar or Monterey Jack work well as substitutes.
Equipment
- Instant Pot (or other electric pressure cooker)
- Wooden spoon or heatproof silicone spatula
- Measuring cups and spoons
- Can opener
- Colander (for draining pasta in variations)
- Optional: kitchen thermometer for checking beef, baking tray if you broil the cheese topping
Helpful tools and extras
- If you like a smoother sauce, a quick pulse with an immersion blender after pressure cooking can create a creamier texture.
- A baking tray and broiler can help get a bubbly, browned cheese topping if desired.
Step-by-Step Instructions (with tips)
-
Set Instant Pot to saute mode and add the 1 lb. ground beef and 1/2 teaspoon of the salt. Stir often until all the beef is browned. This should take about 5 minutes; break the meat into small pieces as it cooks so it cooks evenly.
- Tip: Don’t add oil unless your beef is very lean — the fat will render out as it browns.
- Tip: Use a thermometer if you want to check doneness; ground beef should reach 160°F (71°C).
-
Press cancel and carefully drain excess fat from the pot. Use tongs or a spoon to hold the meat while pouring out fat, or tilt the pot slightly with heatproof gloves and blot with paper towels. Return the meat to the pot.
-
Sprinkle 2 tablespoons chili powder, 1/2 tablespoon cumin, and the remaining 1/2 teaspoon salt over the browned meat. Stir briefly just to distribute the spices across the beef.
- Tip: Blooming the spices on the hot meat for 30 seconds helps them release more aroma and flavor.
-
Add the 2 1/2 cups elbow macaroni on top of the seasoned meat. Do not stir. Layering helps prevent pasta from clumping and sticking to the bottom of the pot.
-
Pour 3 1/2 cups water over the macaroni and press down gently so all the pasta is submerged. Make sure there are no dry pockets of noodles above the liquid — complete submersion ensures even cooking.
- Tip: If your macaroni floats, press it down with a spoon so it’s fully covered.
-
Add the 8 oz can of tomato sauce and the 14.5 oz can of diced tomatoes with green chilies right on top in the center. Do not stir. Leaving the sauce and tomatoes layered on top helps prevent the burn warning that sometimes appears on electric pressure cookers.
- Tip: If you ever get a “burn” message, cancel, stir gently to release any stuck bits, and ensure you’re using enough liquid.
-
Secure the Instant Pot lid and make sure the vent is set to sealing. Pressure cook (the “manual” setting on some models) on high for 4 minutes.
- Tip: Because the pot must come to pressure before the timer starts, the total cook time will be a few minutes longer — expect roughly 12–15 minutes total including pressurizing.
-
When the timer is complete, perform a quick release of the pressure by carefully moving the vent to venting. Be cautious of the steam.
-
Remove the lid and stir the contents well. The sauce will begin to thicken as the hot liquid incorporates with the pasta and tomatoes. If it seems too thin, letting it sit while you shred cheese will thicken it further.
- Tip: If the sauce is very thin, press the Instant Pot back to saute for 2–3 minutes and stir continuously to reduce.
-
Add 1 cup of shredded colby jack cheese and stir it in so it melts into the sauce and becomes creamy.
- Variation: For a browned topping, transfer the chili mac to a baking dish, sprinkle additional cheese on top, and broil 2–3 minutes until bubbly and golden. Watch closely to avoid burning.
-
Serve hot with additional shredded cheese on top, chopped green onions, sour cream, or sliced avocado if you like. Enjoy!
Helpful technique and variations
- To make this recipe with ground turkey or plant-based crumbles, brown exactly the same way but expect slightly different flavor and fat content; add a tablespoon of olive oil if using lean proteins.
- For extra depth, stir in a tablespoon of tomato paste when you add the spices.
- If you prefer a creamier texture, stir in 1/2 cup sour cream or cream cheese after adding the shredded cheese.
- Cooking pasta perfectly: if you want firmer pasta, reduce pressure cook time by 1 minute (3 minutes), but note the pot’s pressurizing time is unchanged, so test and adjust slightly with your model.
If you enjoy making more Instant Pot meals, this recipe sits well alongside other one-pot favorites like Instant Pot French Onion Soup that also maximize flavor with minimal fuss.
Storage, Freezing & Make-Ahead Tips
Storing leftovers
- Refrigerate leftover chili mac in an airtight container within two hours of cooking. It will keep for 3–4 days.
- Reheat gently on the stovetop over low heat with a splash of water or broth to loosen the sauce, or microwave in 30–45 second intervals stirring between to prevent hot spots.
Freezing
- For longer storage, portion into freezer-safe containers or heavy-duty freezer bags. Squeeze out excess air and freeze for up to 3 months.
- Thaw overnight in the refrigerator before reheating. Reheat on the stovetop over low heat, adding a splash of water to refresh the sauce.
Make-ahead tips
- You can brown the beef and prep the spices the night before to save 10–15 minutes when you’re ready to cook.
- For meal prep, cook the entire recipe and portion into individual containers for grab-and-go lunches or single servings for busy nights.
- If freezing individual servings, leave the cheese out and add freshly shredded cheese when reheating for the best texture.
Portioning advice
- This recipe yields about 4 hearty servings. If you need more, it scales well — increase pasta, meat and liquid proportionally, but keep pressure cooking time roughly the same for similar pasta shapes.
How to Use / Serve This Dish
Serving ideas
- Classic: top with extra shredded colby jack, chopped cilantro, and a dollop of sour cream.
- Tex-Mex twist: serve with warm corn tortillas, lime wedges, and pickled red onions.
- Family-friendly: load up with diced avocado, tortilla chips, and a drizzle of hot sauce for a fun taco-night vibe.
- Kid-friendly: hold back the green chiles or use plain diced tomatoes if younger eaters prefer milder flavors.
Pairings
- A crisp green salad with a citrus vinaigrette balances the richness of chili mac.
- Cornbread or garlic bread are excellent for sopping up sauce.
- For beverage pairings, a malty amber ale or a medium-bodied red wine like Zinfandel complements the chili spices nicely.
Creative variations
- Swap ground beef for shredded rotisserie chicken and reduce spices for a lighter version.
- Stir in a can of drained black beans or corn kernels for added texture and nutrition.
- Make it vegetarian by using plant-based crumbles and a cup of vegetable broth plus a splash of soy sauce for umami.

FAQ
Q: Can I use a different type of pasta?
A: Yes. Short, sturdy pastas like shells, rotini, or penne work well. Keep in mind different shapes may absorb liquid differently; small changes in water (plus or minus 1/4 cup) can help. Cooking time under pressure generally stays the same for similar small pasta shapes.
Q: My Instant Pot showed the “burn” notice — what did I do wrong?
A: The “burn” message usually means something stuck to the bottom or there wasn’t enough liquid. Layering the pasta and keeping the sauce on top (as this recipe instructs) minimizes that risk. If it happens, cancel, let pressure release, open, stir to loosen any stuck bits, and ensure enough liquid before re-sealing.
Q: How can I reduce sodium or spice for picky eaters?
A: Use a low-sodium tomato sauce and plain diced tomatoes, and reduce chili powder to 1 tablespoon or omit the green chiles. You can always add more spice at the table for those who want it.
Q: Can I double this recipe for a crowd?
A: You can double quantities, but be cautious with pressure-cooking volume. Don’t fill the pot past the max fill line; you might need to make two batches or use a larger electric pressure cooker. Keep cooking time the same for pasta, but allow extra time for pressurizing.
