Preheat your oven to 400°F (200°C).
On a baking sheet, toss the halved cherry tomatoes with olive oil, salt, pepper, garlic powder, and oregano. Spread them out in a single layer.
Roast the tomatoes in the preheated oven for 20-25 minutes, or until they are soft and slightly caramelized.
Meanwhile, cook the pasta according to package instructions until al dente. Drain and set aside, reserving 1/2 cup of pasta water.
In a large bowl, combine the ricotta cheese, Parmesan cheese, and lemon juice. Mix until well combined.
Add the cooked pasta to the bowl with the cheese mixture. Toss in the roasted tomatoes and fresh basil. If the pasta seems dry, add some reserved pasta water, a little at a time, until you reach your desired consistency.
Serve immediately, garnished with extra basil and a sprinkle of Parmesan if desired.
