15-Minute Tomato-Butter Spaghetti: How It’s Done

Step 1: Cook the Spaghetti
Fill a large pot with water, add a generous pinch of salt, and bring it to a boil. Add the 8 oz of spaghetti and cook according to the package instructions until al dente, usually about 8-10 minutes. Reserve about 1/2 cup of pasta water before draining the spaghetti in a colander.
Step 2: Sauté Garlic and Tomatoes in Butter
While the pasta cooks, melt 2 tablespoons of unsalted butter in a large skillet over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant but not browned. Toss in the halved cherry tomatoes and sprinkle with 1/4 teaspoon of red pepper flakes, salt, and black pepper to taste. Cook the tomatoes for 3-4 minutes, stirring occasionally, until they soften and release their juices, creating a light sauce.
Step 3: Combine Pasta and Sauce
Add the drained spaghetti directly to the skillet with the tomato-butter sauce. Toss well to coat the pasta evenly. If the mixture seems dry, add reserved pasta water a tablespoon at a time until you achieve a silky, saucy consistency.
Step 4: Finish and Serve
Remove the skillet from heat. Tear fresh basil leaves and sprinkle them over the pasta. Serve immediately with a generous grating of Parmesan cheese on top. Enjoy this vibrant, buttery, and lightly spicy spaghetti that’s ready in the time it takes to boil pasta.
Make It Your Way

- Add protein like grilled chicken or pan-seared shrimp for a heartier meal.
- Swap out spaghetti for linguine or fettuccine for a different texture.
- Incorporate other fresh herbs such as parsley or oregano for a flavor twist.
- Stir in a splash of cream or a dollop of ricotta cheese for a creamier sauce.
- For extra depth, add a splash of white wine to the garlic and tomato sauté step.
- Try incorporating toasted pine nuts or walnuts for crunch and nuttiness.
- For a smoky nuance, use smoked paprika instead of red pepper flakes.
Slip-Ups to Skip
- Don’t overcook the garlic; it can become bitter if burnt.
- Avoid under-salting the pasta water—this is your first chance to season the spaghetti thoroughly.
- Be careful not to overcook the cherry tomatoes; they should burst gently but not turn mushy.
- Don’t skip reserving pasta water—it helps the sauce cling to the noodles.
- Avoid adding too much butter; it should enrich the sauce without making it greasy.
Freezer-Friendly Notes
This 15-Minute Tomato-Butter Spaghetti is best enjoyed fresh, as the delicate tomato and butter sauce can separate when frozen. However, if you want to prepare ahead, you can freeze the cooked spaghetti and sauce separately in airtight containers for up to 1 month. Thaw overnight in the refrigerator and gently reheat on the stove, adding a splash of water or broth to bring back the sauce’s silkiness.
15-Minute Tomato-Butter Spaghetti FAQs
Can I use other types of pasta for this recipe?
Absolutely! While spaghetti is classic, feel free to use linguine, fettuccine, or even penne. Different shapes offer varied textures but the sauce will complement them all beautifully.
How spicy is the dish with red pepper flakes?
The 1/4 teaspoon of red pepper flakes adds a gentle heat that enhances the flavors without overwhelming the palate. You can adjust this amount to your spice preference or omit it if you prefer a milder dish.

Yes! Replace the butter with a plant-based alternative like vegan margarine or olive oil. For cheese, use a vegan Parmesan or nutritional yeast to maintain that savory finish.
