Sticky Mongolian Beef Meatballs are a weeknight winner—sweet, savory, and packed with bold garlic-ginger flavor. Juicy meatballs and tender broccoli bake together on one sheet pan for easy cleanup, then get tossed in a thick, glossy Mongolian-style sauce. Serve them over rice or noodles for a comforting, crowd-pleasing meal that’s ready in under 30 minutes.
Meatballs & Broccoli
2 pounds ground beef
4 green onions, finely chopped (plus more for serving)
2-inch piece fresh ginger, grated (or 2 Tbsp ginger paste)
6 cloves garlic, minced or grated
1 head broccoli, cut into florets
1 tablespoon olive oil
Kosher salt and black pepper, to taste
Sauce
1 tablespoon vegetable oil
1 cup low-sodium soy sauce
1 cup brown sugar
4 cloves garlic, minced
2 tablespoons fresh ginger, minced
⅔ cup water
1 tablespoon rice wine vinegar
½ teaspoon red pepper flakes
2 tablespoons cornstarch, whisked with ½ cup water
To Garnish
3 green onions, thinly sliced
Sesame seeds
Preheat oven to 450°F (230°C). Line a baking sheet with parchment paper or foil.
In a large bowl, combine ground beef, green onions, ginger, garlic, salt, and pepper. Mix just until combined. Roll into tablespoon-sized meatballs.
Place meatballs on one side of the baking sheet. Add broccoli to the other side, toss with olive oil, salt, and pepper.
Bake for 15 minutes, or until meatballs are cooked through and broccoli is tender with crispy edges.
While baking, make the sauce: In a large skillet, add vegetable oil, soy sauce, brown sugar, garlic, ginger, water, vinegar, and red pepper flakes. Bring to a simmer over medium-high heat and cook for about 10 minutes.
Stir in the cornstarch slurry and cook until the sauce thickens. Remove from heat.
Add cooked meatballs to the skillet and toss until fully coated in sauce.
Serve meatballs and sauce over rice or noodles. Garnish with green onions and sesame seeds. Serve broccoli on the side.
Less sweet: Reduce brown sugar to ¾ cup for a more savory sauce.
Spice it up: Add extra red pepper flakes or a drizzle of chili oil.
Protein swap: Ground turkey works well—just watch cook time.
Crispier broccoli: Broil for 2–3 minutes at the end of baking.
Meal prep friendly: Sauce thickens more as it cools—perfect for leftovers.
