Ingredients You’ll Need (Nothing Fancy, Promise)

One of my favorite things about this recipe is how approachable the ingredient list is. You might already have most of this in your pantry.

Here’s what you’ll need:

2 pounds frozen fully cooked meatballs
½ cup light brown sugar
¼ cup honey
1 cup jalapeño ketchup
3 tablespoons sriracha sauce
¼ cup soy sauce
3 cloves garlic, minced
Sliced green onions or chopped cilantro (optional, but lovely)

That’s it. No chopping marathons. No specialty store runs. Just simple ingredients coming together in a big, flavorful way.

How to Make Sweet and Spicy Slow Cooker Meatballs (Step-by-Step)

This is one of those recipes where the slow cooker truly earns its counter space. Let’s walk through it together.

Step 1: Add the Meatballs

Pour the frozen, fully cooked meatballs straight into your slow cooker. No thawing required. This is already off to a great start.

Step 2: Make the Sauce

In a medium bowl, whisk together the brown sugar, honey, jalapeño ketchup, sriracha, soy sauce, and minced garlic. The sauce should look smooth, glossy, and smell slightly sweet with a spicy kick.

Step 3: Combine and Cook

Pour the sauce over the meatballs. Gently toss them until they’re fully coated—every meatball deserves some love.

Cover and cook:

LOW for 5–6 hours, or
HIGH for 2–3 hours

During cooking, the sauce thickens, the flavors deepen, and the meatballs soak up all that sweet-spicy magic.

Step 4: Garnish and Serve

Once done, give everything a gentle stir. Sprinkle with sliced green onions or chopped cilantro if you’re feeling fancy (or just want a pop of color). Serve warm and watch them disappear.

Cooking Tips for Perfect Sweet and Spicy Slow Cooker Meatballs

A few little tips can make this recipe even better:

Adjust the heat: If you’re serving kids or spice-sensitive folks, reduce the sriracha slightly. Love heat? Add another tablespoon and live boldly.
Sauce too thick? Add a splash of water or broth near the end. Too thin? Crack the lid for the last 20 minutes and let it thicken up.
Stir once or twice if you can: Not required, but helpful for even coating—especially on LOW.
Double it confidently: This recipe scales beautifully for parties or big families.

And remember, slow cookers are forgiving. This dish won’t punish you if dinner runs late.
