Ingredients You’ll Need

- ½ cup finely diced red onion: Adds sweetness and crunch. Substitute with shallots for a milder flavor.
- ¼ cup sun-dried tomatoes, packed in oil, roughly chopped: Brings tangy richness. If unavailable, use fresh tomatoes for a lighter option.
- ¼ cup halved kalamata olives: Provides a briny punch to balance the dish. Green olives can also work if that’s what you have on hand.

- 3 cups vegetable broth: The cooking liquid that infuses the orzo with flavor. Use low-sodium broth for less salt, or chicken broth if you prefer.
- 1 8-oz block feta cheese: Softens and adds creaminess when baked. Goat cheese can also substitute for a different tang.
- 1 14-oz package frozen plant-based meatballs: We used Impossible Homestyle meatballs, but any frozen variety will work.
- To serve: Lemon zest and crusty bread bring everything together, adding brightness and texture.
How to Make Mediterranean Meatball Casserole Dump and Bake
Preheat and Prepare: Set your oven to 375°F (190°C). While it warms up, lightly grease a large casserole dish (9×13 inches works great).
Dump and Combine Ingredients: In the prepared dish, add 1 lb orzo, ½ cup finely diced red onion, ¼ cup chopped sun-dried tomatoes, ¼ cup halved kalamata olives, 1 pint cherry tomatoes, and 4 minced garlic cloves. Sprinkle in ½ tsp salt, ½ tsp crushed red pepper flakes, ½ tsp oregano, and ¼ tsp black pepper. Pour in 3 cups of vegetable broth, then stir everything together. Nestle 1 block of feta cheese in the center.
First Bake: Tightly cover the dish with aluminum foil and let it bake in the oven for 20 minutes.
Stir and Add Meatballs: Once the time is up, carefully remove the foil and stir the casserole well, breaking up the feta a bit. If the orzo looks dry or isn’t submerged, add an extra cup of broth here. Next, arrange 1 package of frozen plant-based meatballs on top.
Final Bake: Return the casserole to the oven, this time uncovered, for another 15 to 20 minutes. You’ll know it’s ready when the orzo is tender and the meatballs are heated through.
Serve Warm: Dish out the casserole, and if you like, top it with freshly grated lemon zest. Pair it with crusty bread for a satisfying meal.
Storing & Reheating
Store any leftovers in an airtight container at room temperature for up to 2 hours. If you have more leftovers, refrigerate for up to 3 days. For longer storage, freeze in a freezer-safe container for up to 3 months. When ready to enjoy, reheat in the oven at 350°F (175°C) for about 20 minutes, or until warmed through. The texture may vary slightly after freezing, so adding a splash of broth can help refresh it.
Chef’s Helpful Tips
- Make sure to grease the dish well for easy cleanup.
- Mix in extra vegetables like spinach or bell peppers for added nutrition.
- Ensure your meatballs are evenly spaced on top for thorough cooking.
- Add fresh herbs like parsley or basil for flavor right before serving.
- If the orzo absorbs too much liquid while baking, you can add more broth gradually until the desired consistency is reached.
Embrace the Mediterranean vibes and get comfortable in your kitchen with this fantastic casserole. You’ll find it not only fills the bellies of your loved ones but also creates a wonderful gathering point for lively conversations over a shared meal. Experiment with variations and make this dish your own. Enjoy every delightful bite!
