This dish relies on high-quality basics to create a rich, deep flavor profile. The combination of lean beef and fresh vegetables ensures a nutritious result that doesn’t sacrifice taste.

• 1½ lbs lean ground beef
• 1½ tsp salt
• ¼ tsp black pepper
• 1 egg
• 1 Tbsp dried minced onion
• ½ cup breadcrumbs
• 1 Tbsp olive or vegetable oil
• 3 Tbsp all-purpose flour
• 1 15 oz can diced tomatoes with juices
• 1 cup water
• ½ tsp salt
• 2 tsp granulated sugar
• 1 tsp dried basil leaves
• 1½ lbs baby potatoes, halved
• 1 cup carrots, chopped into 3-inch pieces
• 1 medium yellow onion, chopped into large chunks
• 2 celery stalks, chopped

Customizing this casserole is simple with these easy swaps:

• Use gluten-free breadcrumbs or panko if you need a gluten-free meal.
• Substitute 1 ½ Tbsp cornstarch for the flour if you prefer a gluten-free sauce thickener.
• Swap the dried basil for Italian seasoning if you want a slightly more complex herbal note.
• If you don’t have baby potatoes, Yukon Gold potatoes cut into 1-inch chunks work perfectly.
• For a milder flavor, use finely diced fresh onion instead of dried minced onion in the meat mixture.

Step 1: Prepare the Meatball Mixture

In a large bowl, combine the lean ground beef, salt, black pepper, egg, dried minced onion, and breadcrumbs. Mix the ingredients gently until just combined—be careful not to overwork the meat to keep the texture soft—and form into 1-inch meatballs.

Step 2: Brown the Meatballs

Heat the oil in a large skillet over medium heat. Add the meatballs in batches if necessary, browning them on all sides until they develop a nice crust. Remove them from the skillet and set aside.

Step 3: Create the Savory Sauce

Drain most of the excess fat from the skillet, keeping about 3 tablespoons of drippings. Stir in the flour and cook for about one minute to create a light roux. Gradually whisk in the diced tomatoes with their juices, water, salt, sugar, and dried basil. Continue to stir until the sauce begins to thicken.

Step 4: Combine and Bake

Place the halved potatoes, carrots, onions, celery, and the browned meatballs into a large casserole dish. Pour the tomato sauce mixture over everything, stirring gently to ensure the meatballs and vegetables are well-coated. Cover the dish tightly with foil and bake at 375°F for 1 hour, or until the vegetables are tender and the meatballs are cooked through.

Elevate your dinner table by pairing this hearty casserole with the right sides.

• Serve with a basket of warm, crusty bread to soak up the delicious tomato sauce.
• A crisp garden salad with a light vinaigrette balances the richness of the meat.
• Steamed green beans or roasted asparagus add a vibrant touch of color.
• A side of garlic herb butter noodles can make this a truly filling feast.

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm the casserole in the oven at 350°F or in the microwave, adding a tiny splash of water if the sauce has thickened too much in the fridge. For longer storage, you can freeze individual portions for up to 2 months; simply thaw in the refrigerator overnight before reheating.

Can I make this recipe ahead of time?

Yes, you can assemble the casserole completely, cover it, and keep it in the refrigerator for up to 24 hours before baking. Just add an extra 10–15 minutes of baking time if putting it into the oven while cold.

Can I freeze this recipe?

Absolutely! This dish freezes very well. Once cooled, store in freezer-safe containers for up to 2 months.

What can I serve with this recipe?

Crusty bread or a fresh side salad are the best companions. You could also serve it over a bed of mashed potatoes or pasta for a more substantial meal.

How do I keep this recipe from drying out?

The secret is using a tight-fitting foil cover during the entire bake time. This traps steam and ensures the vegetables and meatballs stay moist and delicious.

Instructions

Step 1: Prepare the Meatball Mixture

In a large bowl, combine the lean ground beef, salt, black pepper, egg, dried minced onion, and breadcrumbs. Mix the ingredients gently until just combined—be careful not to overwork the meat to keep the texture soft—and form into 1-inch meatballs.

Step 2: Brown the Meatballs

Cover the dish tightly with foil and bake at 375°F for 1 hour, or until the vegetables are tender and the meatballs are cooked through.

Pro Tips

• Mix the meatball components only until incorporated to ensure they remain juicy and tender.
• Always keep the dish covered during the baking process to prevent the sauce from evaporating and drying out the vegetables.
• Allow the casserole to rest for at least 5 minutes after taking it out of the oven, as this helps the sauce reach the perfect consistency.
• If the sauce seems too thick after baking, add a splash of warm water to loosen it up before serving.

Notes

Store leftovers in an airtight container in the refrigerator for up to 3 days. You can prepare the meatballs ahead of time and keep them refrigerated before assembling the final casserole. Substitute dried basil with Italian seasoning if desired.
