Before you start

Before starting, ensure all ingredients are measured and ready. Brown the ground beef in a skillet over medium-high heat until no pink remains, then drain any excess fat before adding it to the slow cooker.

Dice your onion finely to ensure it softens evenly during the cooking process. If you are using a block of cheddar, shred it yourself to ensure it melts smoothly into the sauce. Having everything prepared will make the assembly process seamless and efficient.

Instructions

Initial Base Assembly

  1. Combine base ingredients
    Add the browned ground beef, diced onion, tomato puree, tomato sauce, beef broth, Italian seasoning, and garlic powder into the slow cooker. Stir well to combine all ingredients thoroughly.
    Look for The mixture should look uniform and well-incorporated.
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip Ensure the beef is thoroughly browned in a skillet before adding it to the slow cooker to develop deeper flavor profiles.

The base assembly is complete when the browned beef, tomato sauce, broth, and seasonings are well-combined in the slow cooker. The mixture should look like a rich, dark red sauce that is ready to begin its slow transformation.

Ensure the onion is evenly distributed throughout the liquid, as this ensures a consistent flavor profile throughout the dish. Once everything is stirred, you are ready to set the slow cooker to low and let the magic begin.

Slow Simmering Phase

  1. Slow cook the sauce
    Cover the slow cooker with its lid and set to cook on LOW for 2.5 hours. This allows the flavors of the tomato and spices to meld beautifully with the beef.
    Look for The sauce will thicken and become fragrant.
    Tip Avoid lifting the lid during the initial cooking time to maintain a consistent temperature.

After 2.5 hours of simmering on low, the sauce should smell deeply savory and aromatic. The volume will have reduced slightly, and the flavors will have concentrated into a robust, hearty base. The onions should be completely translucent and tender. This is the stage where the foundation of your beefaroni is established, creating the perfect environment for the pasta to absorb all that delicious, seasoned liquid in the final phase of cooking.

Final Pasta and Cheese Incorporation

  1. Add pasta and finish
    Stir in the uncooked elbow macaroni, heavy cream, and shredded cheddar cheese. Continue cooking for an additional 30 minutes until the pasta is tender and the cheese is fully melted and glossy. Garnish with chopped parsley and parmesan cheese before serving.
    Look for The sauce should be creamy and the macaroni cooked through.
    Tip Stir occasionally during the last 30 minutes to prevent the pasta from sticking to the bottom of the crockpot.

The final phase is complete when the macaroni is tender and the cheese has completely melted into a glossy, creamy sauce. The beefaroni should look indulgent and thick, with a uniform coating over every piece of pasta. When you pull the spoon through, the sauce should hold its shape slightly and not appear watery. The aroma should be intensely cheesy and savory, signaling that your meal is ready to be ladled into bowls and enjoyed immediately.

Common mistakes

A common mistake is adding the pasta at the very beginning of the cooking process, which will result in mushy, overcooked macaroni. Always wait until the final 30 minutes to stir in the dry pasta.

Another error is using high heat for the entire process, which can scorch the sauce at the edges of the slow cooker. Stick to the low setting as indicated to ensure gentle, even cooking that prevents the dairy from curdling and the cheese from becoming oily.

How to tell it’s done

The beefaroni is done when the elbow macaroni is al dente, meaning it is tender but still retains a slight chew. The sauce should be thick, glossy, and completely emulsified with the melted cheddar cheese and cream.

The internal temperature of the beef should have reached at least 160°F (71°C) during the initial cooking phase. If the pasta is still too firm after 30 minutes, you can continue cooking for another few minutes, adding a splash of broth if the sauce seems too thick.

  • Ground meat: 160°F (71°C) in the thickest part
