Tuna Rigatoni with Sun-Dried Tomatoes — Step-by-Step Instructions

Below are clear step-by-step directions to make this Tuna Rigatoni with Sun-Dried Tomatoes. Follow them in order for the best results.

1. Bring a large pot of salted water to a rolling boil. Add 8oz. whole wheat rigatoni and cook according to package directions until al dente. Reserve about 1/2 cup of the pasta cooking water, then drain the pasta in a colander and set it aside.
2. While the pasta cooks, heat 1 Tbsp olive oil in a large skillet over medium heat. When the oil shimmers, add the 2 minced garlic cloves and 1/2 tsp crushed red pepper flakes. Sauté for about 30–60 seconds, stirring constantly, until the garlic is fragrant but not browned.
3. Add 1/2 cup sun-dried tomatoes (packed in oil, drained and chopped) to the skillet. Sauté with the garlic and red pepper flakes for 1–2 minutes so the tomatoes warm through and release their flavor into the oil.
4. Add the contents of 1 pouch chunk light tuna to the skillet, breaking up the tuna gently with a spoon. Stir to combine and heat the tuna through for 1–2 minutes. If the mixture seems dry, add a splash of the reserved pasta cooking water to loosen the sauce.
5. Turn the heat to low, then add the cooked and drained rigatoni to the skillet. Toss gently to combine so the pasta is coated with the tuna and sun-dried tomato mixture. If needed, add a little more of the reserved pasta water — a tablespoon at a time — until you achieve a glossy, saucy coating.
6. Stir in 2 Tbsp lemon juice and half of the shredded Parmesan cheese (1/4 cup) along with half of the chopped fresh parsley (1/4 cup). Toss for another minute so the cheese melts slightly and the lemon brightens the dish.
7. Remove the skillet from the heat. Taste and adjust seasoning as needed — you can add a pinch of salt or more red pepper flakes if you prefer extra heat.
8. Serve immediately, dividing the pasta among plates or bowls. Sprinkle the remaining 1/4 cup shredded Parmesan and the remaining 1/4 cup chopped fresh parsley over the top for garnish and extra flavor.

Tips for Success

• Do not overcook the rigatoni. Whole wheat pasta can become mushy quickly; aim for a firm al dente bite so it holds up when tossed with the tuna.
• Reserve pasta water before draining. That starchy water is the easiest way to make a silky sauce without adding cream or butter.
• If your sun-dried tomatoes are very dry, rehydrate them in hot water for 10 minutes, then drain and chop. The recipe assumes they’re packed in oil, so they are tender and flavorful.
• For extra green color and a fresh finish, stir in a handful of chopped parsley right before serving.
• Want it cheesier? Stir all the Parmesan into the pasta while it’s still warm so it melts more thoroughly.

Flavor Variations

• Capers: Add 1–2 tablespoons of capers with the sun-dried tomatoes for briny complexity.
• Olives: Stir in sliced Kalamata or green olives for a Mediterranean twist.
• Spinach: Fold in a couple of handfuls of baby spinach at the end and let it wilt into the warm pasta.
• Herbs: Swap half the parsley for fresh basil for a sweeter, aromatic note.

Make-Ahead and Storage

This Tuna Rigatoni with Sun-Dried Tomatoes is best eaten the day it’s made, but you can store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over low heat with a splash of water to loosen the sauce, or microwave in short intervals, stirring between each session. Add a little extra lemon juice and a sprinkle of fresh parsley after reheating to refresh the flavors.

Serving Suggestions

Pair this pasta with a crisp green salad dressed with lemon and olive oil to echo the pasta’s bright notes. A simple side of roasted vegetables or steamed broccolini also makes a wholesome, balanced meal. If you’re hosting, serve the pasta family-style in a shallow bowl and let guests add extra Parmesan at the table.

Notes on Ingredients

• Whole wheat rigatoni offers a nutty flavor and more fiber than regular pasta; measure 8oz. dry for four modest portions or two generous servings.
• Shredded Parmesan cheese enhances the savory depth of the dish. The recipe calls for 1/2 cup, divided, so some flavor melds into the sauce while the rest tops the dish.
• Sun-dried tomatoes packed in oil are more tender and flavorful than dry-packed ones; drain and chop them before adding to the pan.
• Fresh parsley brightens the pasta: use the full 1/2 cup chopped, divided between cooking and finishing.
• Olive oil and lemon juice form a light sauce when combined with the reserved pasta water and Parmesan.
• Crushed red pepper flakes give a subtle kick; adjust the 1/2 tsp amount to your heat preference.
• The pouch of chunk light tuna is already cooked and flaked; add it at the end so it stays tender and flaky rather than breaking down into the sauce.

Nutritional Notes

This pasta balances carbohydrates from whole wheat rigatoni with protein from tuna and fat from olive oil and the sun-dried tomato oil. Using whole wheat pasta increases fiber and keeps you feeling full longer. Lemon and parsley add vitamin C and freshness without additional calories.
