How to Make Slow Cooker Chili Mac with Cheddar and Kidney Beans Recipe
Step 1: Brown the Ground Beef and Peppers
Start by heating a medium skillet over medium-high heat and browning your lean ground beef alongside the chopped sweet baby peppers. This step builds a rich flavor foundation and softens the peppers to bring a gentle sweetness right from the start.
Step 2: Drain Excess Grease
Once browned and perfectly cooked, drain off any excess grease from the beef and peppers. This keeps your chili mac hearty without becoming greasy, ensuring a clean and balanced taste.
Step 3: Combine Ingredients in the Slow Cooker
Transfer the beef and peppers to your slow cooker, then pour in the tomato sauce, Rotel tomatoes, drained kidney beans, chili seasoning, ranch seasoning, and water. Stir everything gently to combine, so every component melds together in the slow cooker’s cozy warmth.
Step 4: Slow Cook to Perfection
Set your slow cooker on low for 6 hours or high for 4 hours. This slow simmer lets all the flavors develop deeply and the beans soften to just the right tenderness, turning your kitchen into a fragrant haven.
Step 5: Add Elbow Macaroni
About 45 minutes before serving, stir in the elbow macaroni. This timing is crucial to ensure the pasta cooks perfectly without becoming mushy, soaking in all those robust chili flavors.
Step 6: Stir in Half of the Cheddar Cheese
Once the macaroni is tender, mix in half of your shredded sharp cheddar cheese. Watch as it melts smoothly into the dish, adding a creamy, cheesy layer that brings everything together.
Step 7: Top with Remaining Cheese and Melt
Sprinkle the rest of the cheddar evenly over the top. Then cover the slow cooker for a few minutes until the cheese beautifully melts into a gooey finish that’s almost too good to resist.
Step 8: Garnish with Fresh Parsley
For a pop of bright green and a touch of freshness, sprinkle chopped parsley over your Slow Cooker Chili Mac with Cheddar and Kidney Beans Recipe just before serving.
Step 9: Serve and Enjoy!
Grab your favorite spoon and dive in. This is comfort food at its most delicious, with layers of flavor that keep you coming back for just one more bite.
How to Serve Slow Cooker Chili Mac with Cheddar and Kidney Beans Recipe

Garnishes
A sprinkle of fresh parsley not only adds a burst of color to your dish but also cuts through the richness, giving you a light, herbal note in every forkful. For extra flair, try dolloping with sour cream or a few sliced green onions.
Side Dishes

Creative Ways to Present
Serve it in individual mini cast iron skillets for a rustic presentation or layer it in a casserole dish topped with extra cheese and breadcrumbs, then bake briefly for a crunchy twist. You can also stuff it into baked bell peppers for a fun and colorful variation.
Make Ahead and Storage
Storing Leftovers
Your Slow Cooker Chili Mac with Cheddar and Kidney Beans Recipe stores wonderfully in an airtight container in the refrigerator for up to 4 days. Keep it chilled until you’re ready to reheat for a quick and tasty meal.
Freezing
This dish freezes beautifully, making it a perfect freezer-friendly meal. Portion it into freezer-safe containers or bags and freeze for up to 3 months. Just thaw overnight in the fridge before reheating.
Reheating

FAQs
Can I use ground turkey instead of ground beef?
Absolutely! Ground turkey is a great leaner alternative that works well in this recipe. Just brown it the same way and proceed with the rest of the steps for equally delicious results.
What if I don’t have ranch seasoning?
If ranch seasoning is missing from your pantry, you can substitute with a mix of dried parsley, garlic powder, onion powder, and dill for a similar zing. It won’t be exactly the same, but it adds a lovely flavor boost.
Can I make this recipe vegetarian?
Yes! Simply skip the ground beef and add extra beans or vegetables like zucchini and mushrooms. Use vegetable broth instead of water if you want more depth, and keep the rest of the spices for that signature chili mac taste.
What type of cheddar cheese is best?
Sharp cheddar cheese is perfect here because it melts nicely and delivers bold flavor. You can mix in milder cheeses like Monterey Jack if you want a creamier, less tangy finish.
How spicy is the dish?
This recipe has a mild to medium heat level thanks to the chili seasoning and Rotel tomatoes. If you prefer it spicier, add chopped jalapeños or a pinch of cayenne pepper to turn up the heat.
