Recipe ingredients

This recipe includes everything needed for homemade barbecue sauce and the meatballs. You can substitute a store-bought BBQ sauce if you prefer a quicker shortcut.

• Ground turkey (lean). You can swap for your preferred ground meat.
• Milk. Any dairy or non-dairy milk works.
• Breadcrumbs. Panko adds light texture; use gluten-free crumbs, oats, or almond flour for alternative diets.
• Egg. Acts as a binder—don’t omit or the meatballs may fall apart.
• Honey. Use any sweetener you prefer.
• Apple cider vinegar. Adds tang to the sauce; white vinegar or white balsamic can be substituted.
• Worcestershire sauce. Adds savory depth; soy sauce, liquid aminos or tamari are good alternatives.
• Basic spices: garlic powder, onion powder, salt and pepper.
• Sub rolls and grated cheese for assembling the subs.

How to make crockpot BBQ meatballs

This is an easy dump-and-go slow cooker method. The meatballs don’t need to be browned first—mix, shape, and add them to the crockpot with the sauce. If you want a head start, make the sauce and roll the meatballs a day ahead.

Pro tip: Prepare the barbecue sauce and form the meatballs in advance to streamline the cooking day.

Make the BBQ sauce:

• Combine tomato sauce, honey, apple cider vinegar, tomato paste, Worcestershire sauce, garlic powder, onion powder, and salt and pepper to taste in a medium bowl.
• Whisk until smooth and well combined. Set aside.

Prepare the meatballs:

1. Lightly spray the inside of the slow cooker with cooking spray.
2. In a large bowl, combine ground turkey, grated onion, minced garlic, breadcrumbs, milk, egg, kosher salt and black pepper. Mix gently with your hands—don’t overwork the meat.
3. Form the mixture into 1½-inch meatballs and place them in the slow cooker in a single layer where possible.
4. Pour the barbecue sauce over the meatballs, reserving about 1 cup if you’d like thicker sauce for serving.
5. Cover and cook on low for 4–6 hours or on high for 2–3 hours, until the meatballs are cooked through and no longer pink in the center.

How to make meatball subs

When the meatballs are cooked, assemble the subs and finish under the broiler for melty cheese and crisp edges.

1. Preheat the oven broiler and place a rack about 6–8 inches from the heat source.
2. Split the sub rolls, fill with 3–4 meatballs each (or your preferred amount), spoon on sauce, and sprinkle with grated cheese.
3. Broil a few minutes until the cheese melts and the bread edges are toasted. Serve with extra sauce if desired.

Recipe FAQs

• Why add milk to meatballs? Milk adds moisture, helping keep meatballs tender. Combined with breadcrumbs it prevents a dense texture.
• Do eggs make meatballs softer? Eggs act as a binder to hold the meatball together; they help texture but are primarily for structure.
• What can replace breadcrumbs? Day-old bread, crushed crackers, quick oats, gluten-free breadcrumbs or almond flour can be used as substitutes.
• What goes on a meatball sub? Classic components are sub rolls, meatballs, sauce (BBQ or marinara), and melted cheese such as provolone or mozzarella.
• What to serve with BBQ meatballs? Serve as sliders or in subs, or alongside mashed potatoes, polenta, rice, coleslaw, or simple salads and roasted vegetables.

Serving suggestions

• Serve with classic coleslaw or a fresh green salad to add brightness and crunch.
• Roasted or air-fried corn on the cob, sweet potato fries, or baked zucchini chips make great sides.
• Offer extra barbecue sauce and pickles on the side for guests who like more tang and texture.

Recipe notes

• Pro tip: Make the sauce and roll the meatballs ahead of time to speed up the final assembly.
• If you use a store-bought barbecue sauce, the recipe becomes even faster—reserve a cup of sauce before cooking if you prefer thicker serving sauce.
• The sauce will thin while simmering in the slow cooker but will thicken as it cools; reserving sauce for serving ensures a thicker finish right away.
• Store leftovers in the refrigerator for 3–4 days. Reheat gently on the stovetop or in the oven until warmed through.
