Mediterranean Lamb and Orzo Casserole
Mediterranean lamb and orzo casserole turns ground lamb, pantry pasta, tomatoes, spinach, olives, and feta into a hearty dinner with very little effort.
This is the kind of weeknight casserole that tastes rich and cozy without feeling fussy. The lamb browns with onion and garlic until savory and fragrant. The orzo bakes right in the tomato broth, so it soaks up every bit of flavor. Salty olives and creamy feta finish the dish with a bright Mediterranean bite.
Why You’ll Love This Recipe
- Big flavor from simple ingredients: Lamb, garlic, oregano, olives, and feta make the casserole taste bold and satisfying.
- One pan comfort: The orzo cooks in the same dish with the tomatoes and broth, which keeps cleanup easy.
- Tender and creamy texture: The orzo turns soft and silky while the feta melts into small salty pockets.
- Naturally balanced: You get protein from lamb, greens from spinach, and slow steady comfort from pasta.
Fabian’s Budget Tip: Ground lamb has a strong, savory flavor, so you can stretch it. Use 12 ounces of lamb and add 1 cup cooked brown lentils when you stir in the orzo. The casserole still tastes rich, but the cost per serving drops.
Ingredients (Serves 4)
- 1 pound ground lamb (450 g)
- 1 medium yellow onion, diced (150 g)
- 4 garlic cloves, minced (12 g)
- 1 1/2 cups dry orzo (300 g)
- 1 can diced tomatoes with juices, 14.5 ounces (411 g)
- 2 1/2 cups vegetable broth (600 ml)
- 4 packed cups fresh spinach (120 g)
- 1/2 cup pitted Kalamata olives, sliced (75 g)
- 1 teaspoon dried oregano (1 g)
- 1/2 teaspoon fine salt (3 g), plus more to taste
- 1/4 teaspoon black pepper (1 g)
- 3/4 cup crumbled feta cheese (110 g)
Step-by-Step Instructions
1. Heat the Oven
Preheat the oven to 375°F (190°C). Use a large oven-safe skillet or a medium casserole dish. If your skillet cannot go in the oven, cook the lamb mixture in a pan first, then move everything to a baking dish before it goes into the oven.
2. Brown the Lamb with Onion and Garlic
Place the ground lamb in a large skillet over medium heat. Add the diced onion. Cook for 6 to 8 minutes, breaking the lamb into small pieces with a spoon. Let it sizzle until the meat turns brown at the edges and the onion looks soft and glossy.
Add the garlic and cook for 30 to 60 seconds. Stop when your kitchen smells warm and garlicky. If there is a lot of fat in the pan, spoon off a little, but leave enough to coat the orzo with flavor.
3. Stir in the Orzo, Tomatoes, Broth, Spinach, Olives, and Oregano
Add the dry orzo to the lamb mixture and stir for 1 minute. The pasta should look lightly coated in the lamb juices. Stir in the diced tomatoes with their juices, vegetable broth, spinach, olives, oregano, salt, and black pepper.
Fold the spinach in by the handful. It will look like too much at first, then it will wilt down into the hot tomato broth. Scrape the bottom of the pan so no browned bits stay stuck. Those bits give the casserole deep flavor.
4. Bake Until the Orzo Is Tender
Cover the skillet or casserole dish tightly. Bake for 22 to 28 minutes, until the orzo is tender and most of the broth has been absorbed. The edges should bubble gently, and the top should look moist, not dry.
If the orzo still feels firm, stir in 1/4 cup hot broth or water and bake for 5 more minutes. Orzo can vary by brand, so trust the texture more than the timer.
5. Finish with Feta
Remove the casserole from the oven. Sprinkle the crumbled feta over the top. Let it rest for 5 minutes so the sauce thickens and the feta softens into creamy, salty pieces.
Taste before serving. Add a small pinch of salt or pepper if needed. The olives and feta bring salt, so add slowly.
Expert Troubleshooting & FAQs
Can I use another ground meat instead of lamb?
Yes. Ground beef works well and gives a similar rich flavor. Ground turkey also works, but it tastes milder. If you use turkey, add a little extra oregano and a pinch more salt after baking.
Why is my orzo still firm after baking?
The dish may need more liquid or a tighter cover. Stir in 1/4 cup hot broth or water, cover again, and bake for 5 to 8 more minutes. The orzo should taste tender but not mushy.
Can I use frozen spinach?
Yes. Thaw it first, then squeeze out the extra water. Use about 1 cup thawed spinach (150 g). If you add it frozen, the casserole can turn watery and the orzo may cook unevenly.
Can I make this casserole ahead of time?
Yes. Assemble it up to the point before baking, cover it, and refrigerate for up to 24 hours. Add 1/4 cup extra broth before baking because the orzo will start to absorb liquid as it sits.
What can I do if the casserole looks too soupy?
Let it rest uncovered for 10 minutes. Orzo thickens as it cools. If it still looks loose, bake uncovered for 5 more minutes until the top looks glossy and the sauce clings to the pasta.
