Oven-Baked Meatballs with Vegetables (One-Pan Recipe)

There’s something magical about a dish that comes together in a single pan and still manages to taste like it took all day. These oven-baked meatballs with vegetables are exactly that — juicy, spiced meatballs nestled into a bed of sweet peppers and onions, all simmered in a light tomato-pepper sauce and finished with a bubbling layer of melted cheese. It’s comfort food at its easiest, and it’s about to become one of your go-to weeknight dinners.

Why You’ll Love This Recipe

• One pan, minimal cleanup. The meatballs, vegetables, and sauce all bake together in the same dish, so you’re not juggling multiple pots.
• Big flavor, simple ingredients. A handful of pantry spices — paprika, cumin, red pepper flakes — turn ground beef into something special without any fuss.
• A trick for extra-juicy meatballs. A splash of sparkling water in the meat mixture keeps the meatballs light and tender instead of dense.
• That golden, melty cheese finish. Removing the parchment paper for the last few minutes lets the Kashar or mozzarella turn beautifully golden on top.
• Great for meal prep. It reheats well, so leftovers taste just as good the next day.

Tools You’ll Need

• Large mixing bowl (for the meatballs)
• Cutting board and sharp knife
• Grater (for the onion and garlic in the meatball mix)
• Oven-safe baking dish, roughly 9×13 inches (23×33 cm)
• Small bowl or measuring cup (for whisking the sauce)
• Parchment paper

Ingredients & Prep

For the Meatballs

• 500 g ground beef
• 1 onion, grated
• 1 garlic clove, grated
• 4 tbsp breadcrumbs
• ½ Turkish tea glass sparkling water (about 50 ml)
• 4–5 sprigs fresh parsley, finely chopped
• 1 tsp black pepper
• 1 tsp paprika
• 1 tsp red pepper flakes
• 1 tsp ground cumin
• Salt, to taste

For the Vegetables

• 2 onions, sliced
• 3 green peppers, sliced
• 2 red capia peppers (or red bell peppers), sliced
• 4 garlic cloves
• 3 tbsp olive oil
• 1 tsp dried oregano
• 1 tsp red pepper flakes
• Salt, to taste

For the Sauce

• ½ tbsp tomato paste
• ½ tbsp red pepper paste
• 1½ cups hot water
• Salt, to taste

For the Topping

• Grated Kashar cheese or mozzarella

Prep tip: Grate the onion and garlic for the meatballs instead of chopping them — this releases their juices directly into the meat, which helps keep the meatballs moist as they bake.

How to Make Oven-Baked Meatballs with Vegetables

• Mix the meatballs. In a large bowl, combine the ground beef, grated onion, grated garlic, breadcrumbs, sparkling water, parsley, black pepper, paprika, red pepper flakes, cumin, and salt. Knead everything together until well combined. Shape the mixture into meatballs slightly larger than a walnut.
• Prepare the vegetable base. Slice the onions and peppers into thin strips and spread them across the bottom of a baking dish. Add the whole garlic cloves, olive oil, oregano, red pepper flakes, and salt, then toss until everything is evenly coated.
• Assemble. Arrange the meatballs on top of the vegetable layer, spacing them evenly.

• Make the sauce. In a small bowl, whisk together the tomato paste, red pepper paste, hot water, and salt until smooth. Pour this sauce evenly over the meatballs and vegetables.

• Cover and bake. Wet a sheet of parchment paper, squeeze out the excess water, and use it to cover the baking dish. Bake in a preheated oven at 180°C (350°F) until the meatballs are cooked through and the vegetables are tender, about 35–40 minutes.
• Add the cheese. Remove the parchment paper, sprinkle the top generously with grated Kashar cheese or mozzarella, and return the dish to the oven for a few more minutes until the cheese is melted and lightly golden.

• Serve. Let the dish rest for a few minutes before serving. It pairs beautifully with crusty bread or steamed rice to soak up the sauce.

Storage

• Refrigerator: Store leftovers in an airtight container for up to 3 days.
• Freezer: The meatballs and vegetables (without the cheese topping) freeze well for up to 2 months. Thaw overnight in the fridge before reheating.
• Reheating: Warm gently in a covered oven-safe dish at 160°C (320°F) until heated through, or use the microwave in short intervals. If reheating from frozen, add a fresh layer of cheese on top during the last few minutes for the best texture.

Frequently Asked Questions

Can I use ground chicken or turkey instead of beef? Yes. Ground chicken or turkey works well in this recipe, though the meatballs will be slightly lighter in flavor. You may want to add an extra pinch of spices to compensate.

What can I use instead of sparkling water in the meatballs? Plain cold water works as a substitute, though the sparkling water helps create a slightly airier texture. Club soda is another good option.

Do I have to use parchment paper to cover the dish? Covering the dish helps trap steam so the meatballs stay juicy and the vegetables cook evenly. If you don’t have parchment paper, you can use an oven-safe lid or aluminum foil instead.

What’s a good substitute for Kashar cheese? Mozzarella, provolone, or a mild cheddar all melt nicely and make good substitutes if Kashar cheese isn’t available.

Can I make this dish ahead of time? Yes. You can shape the meatballs and prep the vegetables a day in advance, then store them separately in the fridge. Assemble and bake just before serving for the best results.

Is this recipe spicy? It has a mild warmth from the red pepper flakes and paprika, but it isn’t intensely spicy. Feel free to adjust the amount of red pepper flakes up or down to suit your taste.
