Baked Feta Pasta with Olives and Spinach is a one-dish dinner where you bake a block of feta with cherry tomatoes and olives until everything turns soft, then mix in cooked pasta and fresh spinach. The oven does most of the work while you boil the pasta.
The tomatoes turn sweet and jammy as they roast, and the feta softens into a sauce you can mash right in the dish. Kalamata olives add a salty, briny bite, and the spinach wilts in at the end so it stays bright green instead of going mushy.
I like this one for busy weeknights because there’s barely any hands-on cooking. You just toss everything in a baking dish, let the oven work, and boil pasta while you wait.
One thing to watch: use a block of feta, not the pre-crumbled kind. Pre-crumbled feta is drier and won’t melt into a smooth sauce, it just stays crumbly on top.

Ingredient Notes
- feta: Use a block of feta packed in brine, not pre-crumbled. Block feta has more moisture and melts into a smoother sauce.
- cherry tomatoes: Halve any large ones so they burst faster in the oven and release more juice for the sauce.
- kalamata olives: Pitted kalamata olives work best here. Green olives are fine too but they taste sharper and more brine-forward.
- baby spinach: Regular spinach works, just chop the leaves roughly first so they mix into the pasta easily.
- short pasta: Penne, fusilli, or shells all hold the sauce well. Avoid long noodles, they don’t pick up the chunky sauce as easily.
- olive oil: Use a decent olive oil since it becomes part of the sauce. Avoid a very bitter or overly peppery one.
Baked Feta Pasta with Kalamata Olives and Spinach
Ingredients
Method
- Heat the oven to 200 C / 400 F.
- In a 23 x 33 cm / 9 x 13-inch baking dish, toss the cherry tomatoes, olives, garlic, olive oil, oregano, red pepper flakes, salt and pepper.
- Push the tomatoes to the sides and set the feta block in the center. Spoon a little of the oil mix over the top of the feta.
- Bake for 30 to 35 minutes, until the tomatoes have burst and the feta is soft and lightly golden on top.
- Meanwhile, bring a 6-quart / 5.7 L pot of salted water to a boil. Cook the pasta according to package directions until al dente, about 10 to 12 minutes.
- Reserve 1 cup / 240 ml of the pasta water, then drain the pasta.
- Remove the baking dish from the oven. Add the spinach and stir it into the hot tomatoes and oil until it wilts, about 1 minute.
- Mash the feta with a fork right in the dish, mixing it with the tomatoes and olives into a chunky sauce.
- Add the drained pasta to the dish and toss well, adding splashes of the reserved pasta water until the sauce coats the noodles.
- Taste and adjust the salt. Feta and olives are already salty, so go easy at first.
- Scatter torn basil over the top and serve warm.
Notes
- Use a block of feta, not pre-crumbled, for a smoother sauce.
- Reserve pasta water before draining, you'll need it to loosen the sauce.
- Taste before salting, feta and olives are already salty.
- Add spinach off the heat so it wilts without turning mushy.
Tips for Success
- Use a block of feta, not pre-crumbled, so it melts into a smooth sauce instead of staying dry and crumbly.
- Reserve at least 1 cup of pasta water before draining, it loosens the sauce so it coats the noodles.
- Add spinach right after the dish comes out of the oven so residual heat wilts it without turning it mushy.
- Taste before adding extra salt, feta and olives are already salty on their own.
- Cut larger cherry tomatoes in half so they burst faster and release more juice into the sauce.
Variations
- Swap kalamata olives for green olives for a sharper, more brine-forward bite.
- Add a drained can of white beans for extra protein and a heartier meal.
- Stir in a handful of sun-dried tomatoes along with the fresh ones for a deeper, sweeter flavor.
Storage and Reheating
Baked feta pasta keeps in the fridge for 3 to 4 days in a sealed container. The sauce firms up as it cools, so don’t worry if it looks a bit dry going in.
To reheat, warm it in a skillet over medium-low heat with a splash of water or milk, stirring until the sauce loosens back up, about 3 to 4 minutes. You can also microwave it in 30-second bursts, stirring between each one.
I don’t recommend freezing this one. The spinach turns watery and the pasta gets soft when it thaws.
Serving Suggestions
Baked feta pasta with olives and spinach is filling enough on its own, but a piece of crusty bread on the side is good for scooping up extra sauce.
A simple green salad with lemon and olive oil balances the richness of the feta. A glass of chilled white wine works well here too, something crisp like a Sauvignon Blanc.
For a bigger spread, add a plate of roasted vegetables or a bowl of olives and marinated artichokes alongside it.
FAQ
Why is my baked feta pasta sauce grainy instead of creamy?
This usually happens when the feta doesn’t melt fully. Low-fat feta or pre-crumbled feta stays dry in the oven instead of softening into a sauce. Use a block of full-fat feta packed in brine and mash it well with the hot tomatoes right after baking.
Can I use crumbled feta instead of a block for this recipe?
You can, but the sauce won’t turn out as smooth. Pre-crumbled feta has less moisture and tends to dry out in the oven instead of melting. A block of feta, mashed after baking, gives you a creamier result.
Can I make baked feta pasta ahead and reheat it later?
Yes, it keeps in the fridge for 3 to 4 days in a sealed container. Reheat it in a skillet over medium-low heat with a splash of water or milk to loosen the sauce, or microwave it in short bursts, stirring in between.
What goes well with baked feta pasta with olives and spinach?
Crusty bread is good for soaking up extra sauce, and a simple green salad with lemon balances the richness of the feta. A crisp glass of white wine also works well alongside this dish.
Is baked feta pasta with olives and spinach vegetarian?
Yes, this dish is vegetarian since it’s built from feta, olives, tomatoes, spinach, and pasta with no meat. For a gluten-free version, just swap in your favorite gluten-free short pasta and cook it according to the package directions.
How is this different from the classic baked feta pasta recipe?
The classic version is usually just a warm baked feta with tomatoes and pasta. This one adds kalamata olives for a briny bite and spinach for color and freshness, so the flavor is saltier and a bit more savory overall.
