Here’s all you need:

Step-by-Step Instructions
If you’re wondering how long to cook frozen meatballs in crockpot and want a method that works every single time, this is it. Whether you’re prepping dinner before work or setting up for a game-day snack, these steps make it easy.
Step 1 – Prep the Crockpot
Pour the frozen meatballs into your slow cooker. Then add your sauce of choice and stir to coat every meatball evenly. Don’t worry if they’re stuck together—they’ll separate as they heat.
Step 2 – Choose Cook Setting
- HIGH for 2–4 hours
- LOW for 4–6 hours
The most important part? Make sure the internal temperature of the meatballs reaches 165°F before serving.
Step 3 – Stir Occasionally
If you’re home, give them a gentle stir once or twice during cooking. It helps the sauce distribute and ensures even heating.
Step 4 – Hold on Warm
Once fully cooked, switch your crockpot to “Warm.” You can leave them here for up to 3 hours if you’re not ready to serve just yet.
Helpful Tips for How Long to Cook Frozen Meatballs in Crockpot
Once I knew how long to cook frozen meatballs in crockpot, I realized the how mattered just as much as the when. These little adjustments make a big difference in flavor and texture:
- Start on high (if possible) – For the first hour, it helps bring the meatballs out of the food safety danger zone faster.
- Use enough sauce – Don’t skimp! A good coat of sauce keeps everything moist and flavorful.
- Avoid overcrowding – Give those meatballs some room so they heat evenly. I use a 5–6 quart crockpot for a standard bag.
- Use a thermometer – The internal temperature should hit 165°F. It’s the only way to guarantee they’re fully safe to eat.
- Thicker sauces work best – BBQ and marinara coat beautifully and hold up well. Watery sauces tend to get thin and lose flavor during the slow cook.

Once I figured out how long to cook frozen meatballs in crockpot, the next question became: what do I serve them with? Whether it’s a Tuesday night or game day, these pairings keep things tasty and simple:

- Sandwich-ready: Pile them into toasted sub rolls, add mozzarella or provolone, and melt under the broiler for instant meatball subs.
- Hearty main dish: Spoon them over mashed potatoes, rice, or pasta for a filling and cozy meal.
Or keep things hearty and wholesome with one of our favorite plant-based crockpot meals.
