Detailed Directions and Instructions
Step 1: Preheat the Oven
Preheat your oven to 425 degrees Fahrenheit.
Step 2: Prepare the Sheet Pan Ingredients
On a sheet pan, combine 12 ounces of cherry or grape tomatoes, 8 ounces of washed and quartered fresh white button mushrooms, and half of a roughly chopped onion.
Step 3: Season the Vegetables
Drizzle the vegetables with 1 tablespoon of olive oil and sprinkle with 1/2 teaspoon of salt to ensure even seasoning.
Step 4: Roast the Vegetables
Place the sheet pan in the preheated oven and roast the vegetables for 20 minutes, until they are tender and lightly caramelized.
Step 5: Cook the Spaghetti
While the vegetables are roasting, bring a large pot of salted water to a boil. Cook 1 pound of spaghetti according to the package directions. Before draining, reserve 1/2 to 1 cup of pasta water. After draining, toss the pasta with a little butter or olive oil to prevent sticking.
Step 6: Make the Sauce
Once the vegetables are roasted, transfer them to a food processor. Add in the 14-ounce can of diced tomatoes, 2 cloves of garlic, 1/2 teaspoon of salt, and 1/2 cup of pitted olives (if using). Also, add 3 tablespoons of olive oil and the juice of 1 lemon. Pulse the mixture until a textured sauce forms. Taste the sauce and adjust seasoning if necessary.
Step 7: Combine Pasta and Sauce
In a large bowl, combine the cooked spaghetti with the roasted vegetable sauce. Gradually add the drained and rinsed 2-ounce jar of capers and 1/4 cup of butter, mixing well. Incorporate the reserved pasta water a little at a time until the pasta is combined with the sauce and reaches a desired saucy consistency.
Step 8: Serve the Dish
Plate the pasta and top with fresh basil leaves or freshly grated Parmesan cheese, as desired.
Notes
Note 1: Adjust Seasoning
Feel free to taste the sauce as you prepare it. Don’t hesitate to adjust the salt, pepper, or lemon juice according to your personal preference.
Note 2: Additional Garnishes
For added richness, consider drizzling a bit more olive oil over the finished dish or adding crushed red pepper flakes for a spicy kick.
Note 3: Storing Leftovers
Store any leftovers in an airtight container in the refrigerator. This dish can be enjoyed again and may taste even better once the flavors meld further.
Note 4: Pasta Water Importance
The reserved pasta water helps to adjust the sauce’s consistency. Use it sparingly, adding just enough to achieve the desired texture.

Cook techniques
Roasting
Roasting enhances the natural sweetness of tomatoes and mushrooms. Ensure the oven is preheated to 425°F to get a good caramelization. Use olive oil and salt to bring out the flavors.
Cooking Pasta
Cook spaghetti according to the package directions, ensuring it is al dente. Reserve some pasta water to help adjust the sauce consistency later.
Blending for Sauce
Use a food processor to combine roasted vegetables, canned tomatoes, garlic, olives, olive oil, and lemon juice. Pulse until a textured sauce forms, adjusting flavors as necessary.
Tossing Pasta
Combine the cooked pasta with the sauce, adding capers, butter, and reserved pasta water gradually. Toss until the pasta is evenly coated and the sauce reaches the desired consistency.
