1-First Step: Prepare the Shrimp Stock Begin by combining the shrimp peels, 2 cups water, a few sprigs of parsley, 6-8 whole peppercorns, 6 cloves garlic, and a pinch of salt in a stockpot. This step builds a flavorful base for your spicy shrimp pasta with garlic. Bring it to a boil over high heat, then lower to a simmer for 10 minutes to let the flavors meld.

2-Second Step: Cook the Pasta While the stock simmers, boil a pot of salted water. Add 8 ounces of linguine, capellini, or spaghetti and cook it 1-2 minutes less than the package says for an al dente texture. For dietary tweaks, use gluten-free pasta if needed. Drain the pasta and set it aside, reserving a bit of the water to adjust sauce consistency later in your garlic shrimp pasta.

3-Third Step: Simmer the Sauce Heat 2 tablespoons olive oil in a large skillet over medium-high heat. Slice the remaining 6 cloves garlic and add them along with ½ to 1 teaspoon red pepper flakes for that signature spice. Let it sizzle for about 1 minute to infuse the oil, adapting the heat based on your preference for a milder shrimp pasta with fresh tomato sauce.

4-Fourth Step: Build and Thicken the Sauce Add ¾ cup of the reserved shrimp stock to the skillet and bring it to a simmer. Then, mix in 1 ½ cups halved grape or cherry tomatoes and 1 (14.5-ounce) can diced tomatoes. Season with salt and black pepper, cover the pan, reduce heat to low, and cook for 10 minutes. For low-calorie options, you could reduce the tomatoes slightly. Remove the lid, raise the heat to medium, and cook for another 5 minutes to thicken, creating a rich base for your spicy garlic shrimp pasta.

5-Fifth Step: Add and Cook the Shrimp Stir in the 1 pound raw shrimp and cook for 2 minutes until they start to turn pink. For pescatarian adaptations, this step works as is, but if you’re going vegan, swap in tofu here and adjust cooking time. Add 2 tablespoons cold butter and stir until it melts, then cook the shrimp for another 30-60 seconds until fully done, ensuring they’re tender and flavorful in your tomato sauce pasta.

6-Sixth Step: Combine and Finish Adjust seasoning with more salt, pepper, or red pepper flakes as desired. Toss in the cooked pasta and mix everything together, adding a splash of the remaining shrimp stock if the sauce is too thick. For added variety, incorporate fresh spinach at this stage for extra nutrients. Finally, garnish with chopped parsley and Parmesan cheese before serving your spicy garlic shrimp pasta hot.

7-Seventh Step: Serve and Enjoy This step is all about plating: divide the pasta into bowls and top with more cheese if you like. It’s a great time to add lemon juice for brightness, making the dish even more versatile. If you’re serving for a crowd, this spicy shrimp pasta with garlic pairs well with sides, and remember, cooking it slightly underdone lets the pasta absorb the sauce fully.
