Greek Spaghetti with Tomatoes and Feta

Bright, simple, and impossibly satisfying, Greek Spaghetti with Tomatoes and Feta is my kind of weeknight dinner. It comes together fast, relies on pantry-friendly ingredients, and sings with olive oil, lemon, and tangy feta. This version keeps things light but generous—there’s enough lemon and herbs to brighten every forkful, and crumbled cheese adds a creamy, salty finish that pairs beautifully with perfectly cooked thin spaghetti.

This recipe is built from modest, everyday components: olive oil, oregano, garlic, diced tomatoes, green onions, parsley, lemon juice, thin spaghetti, and feta. No complicated technique required—just good timing so the sauce and pasta meet when both are hottest and most fragrant. Whether you’re cooking for one, feeding a small family, or bringing a simple but impressive dish to a potluck, this pasta checks all the boxes.

Why this recipe works

There are a few small things that make a big difference. First, toasting dried oregano briefly in warm olive oil releases essential oils and deepens flavor. Next, cooking garlic only until fragrant prevents bitterness and keeps the sauce fresh. Using hot cooked pasta helps the sauce cling to the noodles so each bite is saucy and coated. Finally, folding in fresh herbs and lemon at the end keeps brightness and prevents them from turning dull in heat.

Ingredients

• 2 teaspoons olive oil
• 1 teaspoon dried oregano
• 1 large garlic clove, minced
• 3 cups diced tomatoes
• ½ cup sliced green onions
• ¼ cup chopped fresh parsley, divided
• 2 tablespoons freshly squeezed lemon juice
• 4 cups (8-ounces uncooked pasta) hot cooked thin spaghetti
• 1 cup (4-ounces) crumbled feta cheese, divided
• freshly ground black pepper, to taste
• lemon slices, for garnish (optional)
• thinly sliced green onion, for garnish (optional)

Equipment

• Large pot for boiling pasta
• Large skillet or sauté pan
• Colander
• Measuring spoons and cups
• Wooden spoon or spatula
• Tongs

Prep and timing

Total hands-on time is about 15–20 minutes with roughly 20–25 minutes from start to finish if you include pasta cooking time. Have the pasta water boiling near the time you begin the sauce so you can combine them while hot.

Step-by-step instructions

1. Bring a large pot of salted water to a rolling boil for the thin spaghetti. Cook the pasta according to package directions until al dente. Before draining, reserve a small cup of the starchy pasta water; then drain the pasta and keep it hot. The recipe calls for 4 cups (8 ounces uncooked) hot cooked thin spaghetti.
2. While the pasta cooks, add 2 teaspoons olive oil to a large skillet and warm it over medium heat. When the oil shimmers, add 1 teaspoon dried oregano and stir it in the oil for about 20–30 seconds. Toasting the oregano briefly helps release its flavor but avoid letting it burn.
3. Add 1 large garlic clove, minced, to the skillet. Sauté the garlic with the oregano and oil for about 30–60 seconds, just until it becomes fragrant. Stir constantly so the garlic softens but does not brown.
4. Pour in 3 cups diced tomatoes. Increase the heat to medium-high and let the tomatoes simmer gently for 3–4 minutes so they warm through and begin to break down. Stir occasionally. If the tomatoes are very watery, simmer a little longer to concentrate the flavors; if they seem dry, add a tablespoon of the reserved pasta water.
5. Stir in ½ cup sliced green onions and 2 tablespoons freshly squeezed lemon juice. Let the mixture cook together for another 1–2 minutes so the green onions soften slightly and the lemon brightens the sauce.
6. Fold in ¼ cup chopped fresh parsley, reserving a tablespoon or two for garnish if you like. Mix well so the parsley distributes through the tomato mixture.
7. Add the hot cooked thin spaghetti to the skillet with the tomato mixture. Toss or use tongs to coat the pasta thoroughly so the sauce clings to the strands. If the pasta seems dry, add a tablespoon or two of the reserved pasta water until you reach the consistency you prefer.
8. Remove the skillet from the heat. Stir in ¾ cup (three quarters of the 1 cup) crumbled feta cheese so it warms and begins to melt slightly into the hot pasta and sauce. Taste and season with freshly ground black pepper to your liking. The feta provides saltiness, so no additional salt is usually needed, but adjust if desired.
9. Transfer the pasta to serving bowls or a platter. Sprinkle the remaining ¼ cup crumbled feta on top along with the reserved parsley and optional thinly sliced green onion for extra crunch and color. Garnish with lemon slices if you like a decorative, citrusy touch.
10. Serve immediately while hot. This dish is best enjoyed right away when the pasta is warm and the feta is slightly creamy against the tomatoes and herbs.

Taste and variations

This recipe is flexible. For extra brightness, add a teaspoon of lemon zest with the lemon juice. If you want more herb flavor, increase the fresh parsley up to ½ cup and consider stirring in a tablespoon of chopped fresh dill. For a bit of heat, add a pinch of red pepper flakes when cooking the garlic. If you like more olive-forward flavor, finish with a light drizzle of extra virgin olive oil over the plated pasta.

Make-ahead and storage

You can prepare the tomato mixture up to one day ahead and refrigerate in an airtight container. Reheat gently on the stovetop, add the hot cooked pasta, and finish with feta and parsley just before serving. Leftovers keep for up to 2 days in the refrigerator. When reheating, add a splash of water or olive oil to loosen the sauce and refresh its texture. Note that the feta will firm up in the fridge, so stir it in while warm to soften.

Serving suggestions

Serve Greek Spaghetti with Tomatoes and Feta with a crisp green salad, warm crusty bread, or a simple cucumber and tomato salad. A side of roasted vegetables—like zucchini or eggplant—complements the fresh, lemony flavors nicely. If you’re feeding a crowd, double the recipe and keep the sauce warm in a low oven or covered skillet, tossing with fresh pasta as needed.

Notes on ingredients

This recipe lists 1 cup (4 ounces) crumbled feta cheese, divided, so you add the majority while the pasta is hot and reserve a quarter cup to finish the dish for texture and visual appeal. The measurement for pasta is 4 cups once cooked, which comes from 8 ounces uncooked thin spaghetti. Using thin spaghetti helps the sauce cling to the strands for a balanced bite of pasta, tomato, and feta.

Frequently asked questions

Can I use canned tomatoes? Yes. If fresh diced tomatoes aren’t available, canned diced tomatoes drained slightly will work well. Taste and adjust cooking time—canned tomatoes may be slightly softer and can break down faster.

Can I make this gluten-free? Absolutely. Swap the thin spaghetti for a gluten-free thin pasta of equivalent weight. Cook according to the package directions and follow the recipe the same way.

Is it ok to add protein? Yes. If you want to add a protein, pan-seared fish or simply roasted chickpeas make great additions. Add proteins after the pasta has been tossed with the sauce so everything stays warm.

Final thoughts

Greek Spaghetti with Tomatoes and Feta is a masterpiece of minimal ingredients and maximum flavor. It’s easy enough for busy weeknights and pretty enough for company. The mix of citrus, herbs, and salty feta creates a bright, Mediterranean-inspired pasta you’ll return to again and again. Give it a try tonight — it’s the sort of recipe that becomes a favorite after just one forkful.
