Begin by preheating your oven to 200°C (400°F). This will ensure it's hot and ready for roasting.
In a medium baking dish, combine the halved cherry tomatoes, minced garlic, and crumbled feta cheese. Drizzle the olive oil over the top, then sprinkle with dried oregano. Season generously with salt and freshly cracked black pepper to enhance the flavors.
Place the baking dish in the preheated oven and let it bake for 25-30 minutes. You're looking for the tomatoes to blister and the feta to become soft and melty.
While the feta and tomatoes are roasting, cook the pasta according to the package instructions until al dente. Once cooked, drain the pasta but be sure to reserve about 1/2 cup of the starchy pasta water for later.
When the feta and tomatoes are beautifully roasted, remove the baking dish from the oven. Use a fork to gently mash the feta and tomatoes together, blending them into a creamy, delicious sauce.
Add the cooked pasta to the baking dish, along with the reserved pasta water. Toss everything together vigorously until the pasta is well-coated with the creamy mixture, ensuring every bite is flavorful.
Taste the dish and adjust the seasoning as needed. Feel free to add more salt, pepper, or a touch of lemon zest for brightness!
To serve, plate the creamy pasta while hot and garnish with fresh basil leaves on top for a delightful finish.
