Before you start

Before starting, ensure your slow cooker insert is clean and dry. Prepare the vegetables by slicing the green bell peppers and onions into long, thin strips, aiming for a consistent size to ensure even cooking. Have your steak seasoning ready in a small bowl for easy application.

If your provolone cheese sauce is cold from the refrigerator, you may want to bring it to room temperature for a few minutes, though it is not strictly necessary as the slow cooker will heat it through thoroughly during the long cooking cycle.

Ingredients at a glance (5)
  • 2 lb frozen precooked beef meatballs
  • 2 cups green bell pepper strips
  • 1 cup onion strips
  • 2 tbsp steak seasoning
  • 1 1/2 cups provolone cheese sauce, store-bought or made ahead

Instructions

Layering the base

  1. Prepare the slow cooker
    Add the frozen beef meatballs to the base of the slow cooker insert. Ensure they are evenly distributed to allow for uniform cooking throughout the process.
    Look for Meatballs cover the bottom of the slow cooker insert
    Tip Keep the lid on as much as possible to maintain heat.

The meatballs are evenly spread across the bottom of the slow cooker. This initial layer is crucial as it creates a stable foundation for the vegetables and sauce, ensuring that the heat is distributed efficiently throughout the cooking process.

Check that the meatballs are not piled too high in the center to maintain a consistent cooking depth.

Adding aromatics

  1. Layer the vegetables and seasonings
    Arrange the green bell pepper strips and onion strips over the top of the meatballs. Sprinkle the steak seasoning evenly across the vegetables and meatballs to ensure flavor coverage.
    Look for Vegetables are layered over the meatballs
    Tip Uniformly cut pepper and onion strips cook more evenly.

The peppers, onions, and steak seasoning are distributed in an even layer over the meatballs. At this stage, the colors should look vibrant and the seasoning should be visible across the surface. Ensure the vegetables are spread out so that they do not clump together, which helps them soften uniformly as the heat rises.

Finishing and heating

  1. Add sauce and cook
    Spoon the provolone cheese sauce over the top of the ingredients. Cover and cook on low for 4 hours until the meatballs reach an internal temperature of 160°F (71°C). Let the meatballs rest for 5 minutes before serving.
    Look for Sauce is bubbly and meatballs are heated through
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip Use a meat thermometer to check the center of the largest meatball.

The cheese sauce is spooned over the top, and the slow cooker is set to low. By the end of this phase, the sauce will be creamy and fully incorporated with the meat juices, and the meatballs will be tender. Check that the sauce has not scorched and that the internal temperature is safe.

Common mistakes

One common mistake is overcrowding the slow cooker, which can prevent the ingredients from heating evenly. Ensure you have enough space for the ingredients to cook properly without overflowing. Another error is failing to slice the vegetables uniformly; uneven pieces will result in some being mushy while others remain raw.

Finally, do not forget to let the dish rest for five minutes after cooking, which allows the sauce to settle and the flavors to integrate fully before you begin serving the meal to your guests.

How to tell it’s done

The dish is ready when the meatballs are heated through and reach a safe internal temperature of 160°F (71°C). The peppers and onions should be soft and tender to the touch, and the provolone cheese sauce should be thick, smooth, and bubbling around the edges of the slow cooker.

Avoid overcooking, as this can cause the meatballs to lose their texture or the cheese sauce to thicken excessively. Always use a meat thermometer in the center of the largest meatball to confirm it is fully cooked.

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