Ingredients You’ll Need
For the Spinach Garlic Mixture:
- 8 ounces fresh baby spinach
- 3 cloves garlic, finely chopped
- 1–2 tablespoons olive oil
For the Meatball Mixture:
- 1 pound ground beef
- 1 pound ground pork
- 2¼ cups bread crumbs
- 3 to 4 eggs (depending on size)
- Splash of milk
- 4 cloves garlic, finely chopped
- ½ cup grated Parmesan cheese
- Salt and pepper to taste
- Cooked spinach-garlic mixture
For Cooking:
- Mozzarella cheese, cut into small cubes
- 2 tablespoons olive oil (for searing)
- 1 jar Rao’s marinara sauce (or your favorite)
Kitchen Equipment You’ll Need
- Large mixing bowl
- Cast iron skillet or oven-safe sauté pan
- Medium skillet (for spinach)
- Cutting board and sharp knife
- Measuring cups and spoons
- Mixing spoon or spatula
- Aluminum foil
- Oven mitts
- Meat thermometer (optional but helpful)
Step-by-Step Instructions
- Preheat and Prep Preheat your oven to 350°F (175°C). This ensures even baking once your meatballs are seared and sauced.
- Cook the Spinach In a medium skillet, heat 1–2 tablespoons of olive oil over medium heat. Add the spinach and cook until wilted. Stir in 3 cloves of finely chopped garlic and sauté for another 1–2 minutes, until fragrant. Remove from heat, chop finely, and set aside to cool.
- Make the Meatball Mixture In a large bowl, combine the ground beef, ground pork, bread crumbs, eggs, splash of milk, 4 cloves of chopped garlic, Parmesan cheese, salt, pepper, and your cooled spinach-garlic mixture. Mix well using your hands or a sturdy spoon until just combined — avoid overmixing to prevent dense meatballs.
- Form and Stuff the Meatballs Scoop out a portion of the mixture and form into a ball slightly larger than a golf ball. Press a cube of mozzarella into the center, then seal the meat around it completely. Repeat until all the meat is used.
- Sear the Meatballs Heat 2 tablespoons olive oil in a cast iron or oven-safe skillet over medium-high heat. Sear the meatballs on all sides until golden brown, working in batches if needed. This step locks in flavor and gives a satisfying crust.
- Bake with Marinara Once all meatballs are seared, return them to the skillet. Pour Rao’s marinara sauce evenly over the meatballs. Cover the skillet with foil and bake in the preheated oven for 20–25 minutes, or until the internal temperature of the meatballs reaches 165°F (74°C).
- Serve and Enjoy Serve hot over a bed of spaghetti, zucchini noodles, creamy polenta, or enjoy them on their own with an extra sprinkle of Parmesan and chopped herbs like basil or parsley.
Recipe Notes & Pro Tips
- Don’t skip searing: It creates an irresistible crust and helps the meatballs hold their shape during baking.
- Fresh mozzarella tip: Use low-moisture mozzarella if you want a less gooey center that doesn’t leak.
- For extra richness: Add a tablespoon of tomato paste to the meat mixture for depth.
- Breadcrumb swap: Use panko for a lighter texture or crushed crackers in a pinch.
- Make it gluten-free: Use gluten-free breadcrumbs and check that your marinara sauce is certified gluten-free.
Variations & Substitutions
- Turkey or chicken: Swap beef and pork for ground turkey or chicken for a leaner version.
- Cheese alternatives: Stuff with fontina, gouda, or provolone for a twist.
- Hidden veggies: Add finely grated zucchini or carrot for extra nutrients (just squeeze out the moisture first).
- Spicy kick: Add red pepper flakes or diced jalapeños to the meat mixture.
- Low-carb version: Skip the breadcrumbs and use almond flour or crushed pork rinds.
How to Store and Reheat
- Refrigerator: Store leftovers in an airtight container in the fridge for up to 4 days.
- Freezer: Freeze meatballs (with or without sauce) for up to 3 months. Let them cool completely, then store in freezer-safe containers or bags.
To Reheat:
- From fridge: Microwave on medium power for 2–3 minutes or reheat in a skillet over low heat.
- From frozen: Thaw overnight in the fridge or reheat from frozen in a covered baking dish at 350°F (175°C) for 25–30 minutes.
Food & Drink Pairings
- Pasta pairing: Classic spaghetti, rigatoni, or penne make the perfect base.
- Side ideas: A crisp Caesar salad, roasted garlic bread, or sautéed green beans.
- Wine suggestion: A medium-bodied red like Chianti, Barbera, or Pinot Noir balances the richness beautifully.
- Non-alcoholic: A sparkling Italian soda or basil lemonade complements the flavors.
Frequently Asked Questions (FAQ)
Q: Can I make the meatballs ahead of time? A: Yes! You can prepare and refrigerate them (uncooked) for up to 24 hours or freeze them raw for future use.
Q: What’s the best way to make them uniform in size? A: Use a large cookie scoop or weigh each meatball for consistent results and even cooking.
Q: Can I cook these entirely on the stovetop? A: While possible, baking ensures thorough cooking without burning the exterior. If stovetop-only, cover and simmer in sauce for at least 20 minutes on low.
Q: Can I double the recipe for a crowd? A: Absolutely! This recipe scales well. Just make sure to sear the meatballs in batches and use a larger baking dish or two skillets.
Q: Is Rao’s marinara the only option? A: Not at all — feel free to use homemade or your favorite jarred sauce. Look for ones with minimal sugar and high tomato content for best results.
