There are certain meals that feel like a warm hug in a bowl. This Slow Cooker Beef and Macaroni is one of them. It combines all the elements of a classic homemade spaghetti dinner—savory ground beef, tender pasta, rich tomato sauce, and plenty of melted cheese—into a single, effortless slow cooker dish. No boiling water. No separate pot for pasta. No draining grease. Just six ingredients, five minutes of prep, and a few hours of waiting.
The magic happens in the slow cooker. The raw ground beef goes in first, followed by dry macaroni, then a simple sauce made from pasta sauce, beef broth, and salt. As the dish cooks, the pasta absorbs the flavorful liquid, the beef gently poaches and breaks apart, and everything melds together into a hearty, satisfying meal. A final stir of shredded cheddar cheese adds creaminess and richness that takes it over the top.
This is weeknight cooking at its best. It is budget-friendly, kid-approved, and perfect for busy days when you want to come home to dinner already waiting. Serve it straight from the slow cooker with extra cheese on top and a side salad or garlic bread. Dinner is done.

Slow Cooker 6-Ingredient Beef and Macaroni
Prep Time: 5 minutes | Cook Time: 2-2.5 hours on HIGH or 4-4.5 hours on LOW | Resting Time: 10 minutes | Total Time:Approximately 2.5-4.5 hours
Yield: 6 servings
Ingredients
-
1½ pounds ground beef (80-90% lean), raw
-
2 cups dry elbow macaroni (about 8 ounces)
-
1 can (24-26 ounces) pasta sauce or tomato basil marinara
-
2 cups beef broth (or water, but broth is best)
-
1 cup shredded cheddar cheese (or Colby Jack), plus more for serving
-
1 teaspoon kosher salt (or to taste)
Instructions
1. Prepare the Slow Cooker:
Lightly spray the inside of a 5- to 6-quart slow cooker with nonstick cooking spray to help with cleanup.
2. Add the Ground Beef:
Break the raw ground beef into small, even pieces and spread it in an even layer over the bottom of the slow cooker. This helps it cook through and mix evenly with the pasta later.
3. Add the Macaroni:
Pour the dry elbow macaroni directly over the raw ground beef, spreading it into an even layer. Do not stir; you want the beef on the bottom and the dry pasta on top at this stage.
4. Make the Sauce:
In a medium bowl or large measuring cup, whisk together the pasta sauce, beef broth, and kosher salt until well combined.
5. Pour Over the Macaroni:
Slowly pour the sauce-and-broth mixture over the dry macaroni, making sure all of the pasta is moistened. Use the back of a spoon to gently press down any dry pasta so it is mostly submerged, but avoid aggressively stirring the layers.
6. Cook:
Cover the slow cooker with the lid. Cook on HIGH for 2 to 2½ hours, or on LOW for 4 to 4½ hours.
7. Stir Halfway Through:
About halfway through the cooking time, quickly lift the lid and give everything a gentle but thorough stir, breaking up any remaining clumps of beef and making sure the macaroni is circulating in the sauce. Replace the lid promptly so you do not lose too much heat.
8. Add the Cheese:
When the macaroni is tender and the beef is fully cooked through, turn the slow cooker to WARM or OFF. Sprinkle the shredded cheddar cheese over the top, then gently fold it into the beef and macaroni until melted and creamy. Taste and adjust the seasoning with a bit more salt if needed.
9. Rest and Serve:
Let the mixture sit, covered, for 5 to 10 minutes to thicken slightly. The sauce will tighten up as the pasta continues to absorb some of the liquid. Serve warm, straight from the slow cooker, with extra cheese on top if desired.
Recipe Notes & Pro Tips
Do Not Stir Before Cooking: Keeping the ground beef on the bottom and the dry pasta on top is intentional. The beef needs direct contact with the bottom of the slow cooker to cook through properly. The pasta needs to be submerged in liquid to cook evenly. Stirring before cooking would mix the raw beef into the liquid, leaving some pieces undercooked.
Broth vs. Water: Using beef broth instead of water adds significant depth of flavor. The broth infuses the pasta and beef with savory richness that water simply cannot provide. If using water, increase the salt slightly and consider adding a teaspoon of beef bouillon or a splash of Worcestershire sauce.
Pasta Sauce Choices: A 24- to 26-ounce jar of your favorite pasta sauce works perfectly. Tomato basil marinara is recommended, but any variety will work. Avoid sauces labeled “chunky” or “garden vegetable,” as larger vegetable pieces can interfere with the pasta’s ability to cook evenly.
The Halfway Stir is Important: This is the only time you will stir the dish before adding the cheese. It ensures that the pasta cooks evenly, the beef breaks apart into small pieces, and nothing sticks to the bottom. Be quick about it—keeping the lid off for too long releases heat and steam.
Pasta Doneness: The macaroni is done when it is tender but still holds its shape. Overcooked pasta becomes mushy. Check at the lower end of the recommended time range (2 hours on HIGH, 4 hours on LOW) to ensure you do not overcook.
Cheese Variations: Sharp cheddar provides the most flavor. Colby Jack melts beautifully and is slightly milder. For a more sophisticated version, try a blend of mozzarella and Parmesan. Avoid pre-shredded cheese if possible, as anti-caking agents can affect melting.
Variations
Spicy Beef and Macaroni: Add ½ teaspoon of red pepper flakes to the sauce mixture. Use a spicy marinara or add 2 tablespoons of sriracha.
Italian Sausage and Macaroni: Substitute the ground beef with 1½ pounds of Italian sausage, removed from its casings. Reduce the salt slightly, as sausage is typically well-seasoned.
Mushroom Beef and Macaroni: Add 8 ounces of sliced cremini mushrooms to the slow cooker along with the ground beef. The mushrooms add earthiness and soak up the sauce beautifully.
Veggie-Packed Version: Add 1 cup of frozen peas, 1 cup of finely chopped bell peppers, or 1 cup of shredded carrots along with the ground beef. The vegetables will cook down into the sauce.
Creamy Beef and Macaroni: Stir in ½ cup of sour cream or cream cheese along with the cheddar cheese for an even creamier, richer result.
Garlic Lover’s: Add 1 tablespoon of garlic powder or 6 cloves of fresh minced garlic to the sauce mixture.
Serving Suggestions
This dish is a complete meal on its own, but it pairs beautifully with:
-
Garlic bread or breadsticks (for sopping up extra sauce)
-
A crisp green salad with a tangy vinaigrette
-
Roasted vegetables like broccoli or zucchini
-
A sprinkle of fresh parsley or basil for color
For a heartier meal, serve alongside Italian sausage links or meatballs.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 5 days. The pasta will continue to absorb liquid as it sits, so the dish will become thicker and more casserole-like over time.
To reheat, add a splash of beef broth, water, or milk to restore the saucy consistency. Reheat in the microwave in 60-second bursts, or warm gently in a covered skillet over medium-low heat.
This dish freezes well for up to 3 months. Cool completely, then transfer to freezer-safe containers. Thaw overnight in the refrigerator before reheating.
Why This Recipe Works
The slow cooker is the perfect vessel for this dish because it allows the pasta to cook directly in the sauce, absorbing flavor as it hydrates. Traditional stovetop macaroni requires boiling the pasta separately in water, which dilutes the flavor and creates an extra pot to clean. This method eliminates both problems.
The layering is key. Raw ground beef on the bottom ensures it gets enough direct heat to cook through. Dry pasta in the middle absorbs the liquid from above. The sauce and broth pour over the top, soaking into the pasta and trickling down to the beef. By the time the dish is finished, everything is perfectly cooked and deeply flavorful.
The halfway stir is the final piece of the puzzle. It redistributes the pasta, breaks up the beef, and ensures even cooking. Without it, the edges of the dish might become dry or overcooked while the center remains underdone.
This recipe is proof that slow cooker meals do not have to be boring or one-note. With a few simple ingredients and a little strategic layering, you can create something that is hearty, satisfying, and bursting with flavor. It is the kind of meal that makes you glad you own a slow cooker—and the kind that will earn a permanent spot in your weeknight rotation.
