There’s something truly comforting about a hearty plate of meatballs, especially when they’re bathed in a rich onion gravy that tastes like it’s been simmering for hours. These Meatballs in Savory Onion Gravy are tender, juicy, and incredibly flavorful, making them perfect for a cozy family dinner or a satisfying meal prep option.

Each bite of these meatballs is soaked in a silky gravy made from slowly caramelized onions and beef broth, creating a depth of flavor that rivals any restaurant dish. Whether you’re serving them over mashed potatoes, egg noodles, or fluffy rice, this is the kind of meal that warms you from the inside out.

Why You’ll Love This Meatballs in Savory Onion Gravy

You’ll fall in love with this dish because it’s a perfect balance of ease and indulgence. The meatballs are baked instead of fried, cutting down on mess and time, while still keeping them deliciously moist. The gravy, with its deep onion flavor, elevates the entire dish to comfort food perfection. It’s also ideal for make-ahead meals since the flavors only deepen with time.

What Kind of Onions Should I Use for the Gravy?

Yellow onions are the best choice for this recipe. They have a natural sweetness that shines once they are slowly caramelized. If you’re in a pinch, white onions work too, but avoid red onions, as they can alter the flavor and color of the gravy. Thin slicing helps them cook evenly and melt right into the sauce.

Ingredients for the Meatballs in Savory Onion Gravy

The ingredients here are simple and wholesome. You likely have many of them already in your kitchen, and each plays a key role in building that classic, home-cooked flavor.

Ground beef
Breadcrumbs
Egg
Milk
Garlic powder
Salt
Black pepper
Yellow onions
Beef broth
All-purpose flour
Butter
Worcestershire sauce

The ground beef is the star, offering richness and hearty flavor. Breadcrumbs and milk keep the meatballs tender, while egg binds everything together. Garlic powder, salt, and pepper season the mix just right. Yellow onions form the base of the gravy, beef broth deepens the taste, and flour thickens it into a luscious sauce. Butter gives a velvety finish, and Worcestershire sauce adds that irresistible umami punch.

How To Make the Meatballs in Savory Onion Gravy

Step 1: Mix and Shape the Meatballs

In a large bowl, combine ground beef, breadcrumbs, milk, egg, garlic powder, salt, and pepper. Mix gently until just combined, then shape into meatballs about 1.5 inches in diameter.

Step 2: Bake the Meatballs

Preheat your oven to 400°F. Line a baking sheet with parchment paper, place the meatballs on it, and bake for 18-20 minutes or until browned and cooked through.

Step 3: Caramelize the Onions

In a large skillet, melt butter over medium heat. Add thinly sliced yellow onions and cook slowly, stirring often, until golden and tender. This should take about 20 minutes. Don’t rush this step—it builds deep, sweet flavor.

Step 4: Make the Gravy

Sprinkle flour over the caramelized onions and stir for 1-2 minutes to remove the raw taste. Gradually pour in the beef broth while whisking to prevent lumps. Stir in Worcestershire sauce and let the mixture simmer until thickened, about 5 minutes.

Step 5: Combine and Simmer

Add the baked meatballs into the skillet with the gravy. Simmer everything together for 10 minutes to let the flavors meld. Serve hot over mashed potatoes, noodles, or rice.
