Before You Start: Tips & Ingredient Notes
- Choosing your tuna. Tuna packed in olive oil is my top choice for this recipe—it’s more flavorful and moist than tuna in water. However, if water-packed is all you have, just be sure to drain it very well and maybe add an extra half-tablespoon of olive oil to the pan.
- Don’t skip the pasta water. I know I already mentioned it, but it’s that important. The starchy, salty water is like magic glue. It helps the sauce cling to the pasta and creates a lovely, cohesive dish instead of a dry pile of ingredients.
- Prep everything first. This recipe comes together fast once you start cooking. Having your garlic sliced, spinach chopped, and lemon zested before you turn on the heat makes the process smooth and stress-free. It’s the classic ‘mise en place’ approach.
- Embrace the whole wheat. Whole wheat pasta has a nuttier flavor and firmer texture than regular pasta. It stands up beautifully to the robust flavors of the tuna and spinach. Just be sure to taste it for doneness a minute or two before the package instructions suggest.
How to Make Whole Wheat Pasta with Tuna and Spinach
Step 1: Bring a large pot of well-salted water to a rolling boil. You want the water to taste like the sea—this is your only chance to season the pasta itself from the inside out. Add the whole wheat pasta and cook according to the package directions, but aim for al dente. It should have a slight bite to it.
Step 2: While the pasta is cooking, heat the 2 tablespoons of olive oil in a large skillet over medium heat. Add the sliced garlic and optional chili flakes. Cook for just about 1 minute, until the garlic is fragrant and just starting to turn golden at the edges. You’ll notice the aroma is incredible—but be careful not to burn the garlic, or it will turn bitter.
Step 3: Now, add the massive pile of fresh spinach to the skillet. It might seem like a lot, but it wilts down dramatically. Use tongs to toss it in the garlicky oil until it’s completely wilted and vibrant green. This should only take 2-3 minutes.
Step 4: Flake the drained tuna into the skillet with the spinach. Add the rinsed capers as well. Gently stir everything together to combine, being careful not to break up the tuna too much—you want nice, distinct flakes. Let this heat through for a minute or two.
Step 5: Right before your pasta is done, use a ladle or a coffee mug to scoop out about 60 ml (1/4 cup) of the starchy pasta water. This is our sauce secret weapon! Drain the pasta, but don’t rinse it—you want all that starch to stay on the noodles.
Step 6: Add the hot, drained pasta directly to the skillet with the tuna and spinach. Pour in the reserved pasta water. Increase the heat to medium-high and use your tongs to toss everything together vigorously. The trick is to toss and shake the pan—you’ll see the water, oil, and starch emulsify into a light, glossy sauce that coats every strand of pasta.
Step 7: Take the skillet off the heat. Now, stir in the fresh lemon zest, most of the lemon juice (save a little to adjust at the end), and the chopped parsley. Give it one final, gentle toss. Taste it—this is crucial. Does it need more salt? Another squeeze of lemon? A crack of black pepper? Adjust to your liking.
Step 8: Serve immediately, dividing the pasta among warm bowls. I love to finish each serving with an extra drizzle of good olive oil and perhaps a little more parsley or black pepper on top. Dig in while it’s hot!
Serving Suggestions
Complementary Dishes
- A simple arugula salad — Toss arugula with a lemon vinaigrette. The peppery bite of the greens is a fantastic, light contrast to the richness of the pasta.
- Garlic-rubbed bruschetta — A slice of toasted, rustic bread rubbed with garlic and drizzled with olive oil is perfect for mopping up any remaining sauce on your plate.
- Roasted asparagus or broccoli — Some simply roasted vegetables on the side make the meal feel even more complete and add another layer of texture.
Drinks
- A crisp Pinot Grigio or Sauvignon Blanc — The bright acidity and citrus notes in these white wines mirror the lemon in the dish and cut through the oil beautifully.
- A light Italian lager — Sometimes, a cold, crisp beer is just the thing. Its effervescence cleanses the palate between bites.
- Sparkling water with lemon — For a non-alcoholic option, the bubbles and citrus are refreshing and keep your taste buds happy.
Something Sweet
- Lemon sorbet — Continuing the citrus theme, a scoop of tangy, clean lemon sorbet is the perfect palate-cleansing finish.
- A few pieces of dark chocolate — A square or two of high-quality dark chocolate (70% or higher) provides a bittersweet, elegant end to the meal.
- Almond biscotti — The nuttiness of the biscotti echoes the whole wheat pasta, and they’re lovely for dipping into a final cup of coffee.
Top Mistakes to Avoid
- Mistake: Overcooking the garlic. Burnt garlic is bitter and will overpower the entire dish. Keep the heat at medium and watch it closely—it should be fragrant and lightly golden, not brown.
- Mistake: Skipping the pasta water. I’m going to sound like a broken record, but without the starchy water, your sauce won’t come together. The ingredients will just sit on top of the pasta instead of clinging to it in a cohesive sauce.
- Mistake: Rinsing the pasta after draining. This washes away all the precious starch that helps the sauce stick. Just drain it and add it straight to the skillet.
- Mistake: Breaking the tuna down to a paste. You want to flake it gently so you get nice, meaty pieces in every bite. Over-stirring will turn it mushy.
Expert Tips
- Tip: Toast the whole wheat pasta. For an even deeper, nuttier flavor, add the dry pasta to your dry skillet over medium heat for a few minutes before boiling it. Toast it, shaking the pan, until it smells fragrant and toasty. Then proceed with boiling. It’s a game-changer.
- Tip: Add the lemon zest and juice off the heat. The vibrant flavor of lemon is delicate. Adding it after you’ve taken the pan off the burner preserves its bright, fresh character. If you cook it too long, it can turn bitter.
- Tip: Let the pasta finish cooking in the sauce. When you add the pasta to the skillet with the pasta water, let it cook together for the final minute. This allows the pasta to really absorb the flavors of the sauce, a technique called ‘mantecatura’.
- Tip: Use the tuna oil. If you’re using tuna packed in olive oil, don’t just drain it down the sink! You can use a tablespoon of that flavorful oil in the pan instead of some of the fresh olive oil for an extra boost of tuna flavor.
FAQs
Can I use frozen spinach instead of fresh?
Absolutely! Thaw a 10-ounce (280g) block of frozen spinach and squeeze out as much water as humanly possible using your hands or a clean kitchen towel. If it’s too wet, it will make your sauce watery. Add it to the pan in place of the fresh spinach and cook for a minute just to heat it through.
How long do leftovers keep?
Leftovers will keep in an airtight container in the refrigerator for up to 2 days. The pasta will absorb more of the sauce, so when reheating, add a tiny splash of water or olive oil to a skillet over low heat to loosen it up again. The microwave can dry it out a bit.
Can I make this recipe gluten-free?
Of course! Simply swap the whole wheat pasta for your favorite gluten-free pasta. The same rules apply—be sure to reserve that starchy pasta water to help create the sauce. Chickpea or lentil pasta would be especially delicious here.
What other herbs can I use?
Parsley is classic, but feel free to experiment! Fresh basil would be lovely in the summer, or a bit of fresh dill or chives. If you only have dried herbs, use about one-third of the amount (so 1 tablespoon dried parsley instead of 1/4 cup fresh) and add it when you’re cooking the garlic to wake up the flavors.
My sauce seems a bit dry. What did I do wrong?
No worries, this is an easy fix! The most common culprit is not using enough pasta water, or the heat wasn’t high enough when you were tossing it to create an emulsion. Just add another splash of warm water (or even a little more olive oil) to the pan and toss it again over low heat until it looks saucy and glossy.
