3-Ingredient Slow Cooker Flag Day Bites
Prep Time: 5 minutes | Cook Time: 2-3 hours on HIGH or 4-5 hours on LOW | Total Time:Approximately 2-5 hours
Yield: 6 servings
Ingredients
-
2 pounds frozen fully cooked pork meatballs
-
1 cup barbecue sauce (your favorite store-bought)
-
¾ cup grape jelly
Instructions
1. Add the Meatballs:
Place the frozen pork meatballs in an even layer in the bottom of a 4- to 6-quart slow cooker. The meatballs can be stacked slightly, but try to keep them mostly in a single layer so they heat evenly.
2. Make the Sauce:
In a medium bowl, whisk together the barbecue sauce and grape jelly until smooth and fully combined. The mixture should be thick but pourable.
3. Coat the Meatballs:
Pour the sauce mixture evenly over the frozen meatballs, using a spatula to scrape out every bit of the glaze. Gently stir to coat the meatballs as much as possible without splashing.
4. Cook:
Cover the slow cooker with the lid. Cook on HIGH for 2 to 3 hours or on LOW for 4 to 5 hours, until the meatballs are heated all the way through and the sauce is bubbling around the edges.
5. Stir and Serve:
Once heated, give the meatballs a good stir to make sure every piece is coated in the glossy sauce. If the sauce looks too thick, thin it with 1 to 2 tablespoons of water and stir again. Switch the slow cooker to the WARM setting for serving. Serve the meatballs straight from the crock pot with toothpicks as an appetizer, or spoon over rice, noodles, or into slider buns for a simple meal.
Recipe Notes & Pro Tips
Frozen Meatballs: Use your favorite brand of frozen fully cooked meatballs. Pork, beef, turkey, or plant-based meatballs all work well. Do not thaw them before adding to the slow cooker.
Barbecue Sauce: Use your favorite barbecue sauce. Sweet, hickory, or honey barbecue sauces work best. Avoid very tangy or vinegar-heavy sauces, which may clash with the grape jelly.
Grape Jelly: Grape jelly provides sweetness and a beautiful glossy sheen. Substitute with apple jelly, apricot preserves, or red currant jelly for a different flavor profile.
Thicker Sauce: If the sauce is too thin after cooking, remove the lid and cook on HIGH for an additional 15-20 minutes to allow some liquid to evaporate.
Add Heat (Optional): For a spicy-sweet version, add ½ teaspoon of red pepper flakes or 1 tablespoon of sriracha to the sauce mixture.
Add Garlic (Optional): Add 1 teaspoon of garlic powder or 2 cloves of fresh minced garlic to the sauce mixture for savory depth.
Variations
Spicy Flag Day Bites: Add ½ teaspoon of red pepper flakes or 1 tablespoon of sriracha to the sauce mixture. The heat balances the sweetness.
Honey BBQ Flag Day Bites: Substitute the grape jelly with ¾ cup of honey. The honey adds a floral sweetness and helps create a sticky glaze.
Cranberry Flag Day Bites: Substitute the grape jelly with ¾ cup of cranberry sauce (whole berry or jellied). The cranberry adds a tart, festive twist.
Apricot Flag Day Bites: Substitute the grape jelly with ¾ cup of apricot preserves. The apricot adds a bright, fruity flavor.
Teriyaki Flag Day Bites: Substitute the barbecue sauce with teriyaki sauce and the grape jelly with ¾ cup of pineapple preserves. The result is a sweet, tangy, Asian-inspired glaze.
Swedish Flag Day Bites: Substitute the barbecue sauce with 1 cup of beef broth and add ½ cup of sour cream during the last 15 minutes of cooking. The result is a creamy Swedish meatball-style dish.

Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 5 days. The sauce will thicken as it cools, and the flavors will continue to meld.
To reheat, place individual portions in the microwave in 60-second bursts, or warm the entire dish in a covered skillet over medium-low heat, adding a splash of water if the sauce has thickened too much.
These meatballs freeze well for up to 3 months. Cool completely, then transfer to freezer-safe containers. Thaw overnight in the refrigerator before reheating.
