Roasted Tomato Garlic Butter Pasta

Sharing is caring!

Sweet roasted cherry tomatoes, soft garlic, butter, and fresh basil turn into a silky sauce that clings to every strand of pasta. The tomatoes bring brightness, the butter smooths everything out, and a small splash of balsamic gives the whole dish a deeper, richer finish. It feels a little luxurious, but the ingredient list stays simple.

This is the kind of pasta that works when you want something comforting without making a heavy cream sauce. The tomatoes do most of the work here. Once roasted, they become jammy and concentrated, and when blended with butter and garlic, they turn into a smooth, glossy tomato butter that coats hot pasta beautifully.

Ingredients

• 1 1/2 lb cherry tomatoes

• 1 whole garlic bulb

• 3 tbsp olive oil

• 1 tsp salt, plus more for pasta water

• 1/2 tsp black pepper

• 1/4 tsp red pepper flakes, or more to taste

• 4 tbsp unsalted butter, softened (vegan butter, optional)

• 1/4 cup fresh basil leaves

• 1 to 2 tsp balsamic glaze

• 12 oz pasta, such as spaghetti, linguine, or fettuccine

• 1/3 to 1/2 cup reserved pasta water

• Freshly grated Parmesan, for serving

• Extra basil, for serving

Instructions

1. Roast the tomatoes and garlic

Preheat your oven to 400°F (200°C).

Add the cherry tomatoes to a baking dish or sheet pan. Drizzle with olive oil and season with salt, black pepper, and red pepper flakes. Toss well so the tomatoes are evenly coated.

Slice the top off the garlic bulb just enough to expose the cloves. Set it on a piece of foil, drizzle with a little olive oil, then wrap it loosely in the foil.

Place the tomatoes and garlic in the oven. Roast for 30 to 35 minutes, or until the tomatoes have burst and look soft and slightly caramelized. The garlic should be very soft when pressed.

2. Cook the pasta

While the tomatoes roast, bring a large pot of well-salted water to a boil. Cook the pasta until al dente according to the package directions.

Before draining, reserve 1/2 cup of the pasta water. Set it aside.

3. Make the tomato butter sauce

Transfer the roasted tomatoes to a blender or food processor. Squeeze the soft roasted garlic cloves out of their skins and add them in. Add the softened butter, basil, and balsamic glaze.

Blend until mostly smooth. Taste the sauce and adjust if needed. Add a pinch more salt, more chili flakes, or another small drizzle of balsamic if you want a slightly deeper flavor.

4. Toss everything together

Pour the warm sauce into a large skillet or pot over low heat. Add the drained pasta and toss well.

Pour in a little reserved pasta water at a time until the sauce loosens and turns glossy. You want it silky enough to coat the pasta without becoming watery.

5. Serve

Divide the pasta into bowls and finish with grated Parmesan and extra basil. Serve right away while the sauce is warm and smooth.

Tips and Tricks

• Use ripe cherry tomatoes for the best flavor. The sweeter they are, the richer and rounder the sauce will taste after roasting.

• Roast the tomatoes until they look collapsed and a little jammy, not just softened. That deeper roast gives the sauce much more flavor.

• Let the garlic cook until fully soft all the way through. If it is still firm in the middle, the sauce can taste harsher than it should.

• Don’t forget to save some pasta water before draining. A few spoonfuls help loosen the sauce and make it coat the pasta better.

• Add the balsamic glaze slowly. A little goes a long way, and you want it to deepen the sauce, not take over.

• Blend the sauce while the tomatoes are warm, not scorching hot. It will come together more smoothly and be easier to handle.

• If the sauce feels too thick, loosen it with a splash of hot pasta water or a drizzle of olive oil.

• If the sauce feels too loose, let it sit over low heat for a minute before tossing with the pasta.

• Finish with freshly grated Parmesan just before serving. It adds saltiness and helps round out the flavor.

• Store leftovers in the fridge for up to 3 days. Reheat gently with a splash of water so the sauce turns silky again instead of drying out.
