Spaghetti With Tuna and Swiss Chard: A Christmas Eve Classic

The memory is etched in my mind: a cozy kitchen filled with the aroma of garlic, olive oil, and the salty tang of the sea. My Nonna Emilia, a force of nature in a floral apron, would be at the stove, stirring a huge pot of something that smelled utterly divine. It was always Christmas Eve, and the Feast of the Seven Fishes was underway. While there were countless dishes, Spaghetti con Tonno e Bietolini always held a special place in my heart – a seemingly simple pasta that exploded with flavor, a testament to the magic of Italian cooking. This wasn’t just a meal; it was family, tradition, and the warmth of the holidays all rolled into one delicious bite.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 30 minutes
• Total Time: 50 minutes
• Servings: 6
• Yield: 6 servings
• Dietary Type: Dairy-Free

Ingredients

• 1 lb swiss chard or 1 lb beet leaf, the leaves torn and the ribs cut into 2-inch pieces
• 1 medium onion, minced
• 1/3 cup extra virgin olive oil, plus additional oil for drizzling over the pasta
• 1/4 cup flat leaf parsley, coarsely chopped
• 1 (13 1/2 ounce) can tuna, packed in olive oil, drained and flaked lightly
• 1 lb spaghetti
• 2 teaspoons white wine vinegar (to taste)
• Salt and pepper to taste

Equipment Needed

• Large saucepan
• Heavy skillet
• Large bowl

Instructions

1. Bring a large saucepan of salted water to a boil. Add the chard ribs and cook for 7 minutes. Then, add the chard leaves and cook for an additional 3 minutes. The ribs should be tender but still have a slight bite.

2. Drain the chard immediately and rinse it under cold water to stop the cooking process. This helps to preserve the vibrant green color and prevent it from becoming mushy. Thoroughly pat the cooked chard dry between paper towels. Removing excess water is crucial for achieving the right texture in the finished dish.

3. Finely chop the chard. At this point, the prepared chard can be stored in a zip-lock plastic bag in the refrigerator for up to 2 days. This make-ahead step is a lifesaver during busy holiday preparations.

4. In a heavy skillet, heat 1/3 cup of extra virgin olive oil over moderately low heat. Add the minced onion and cook, stirring frequently, until it is softened and translucent, about 5-7 minutes. Don’t rush this step; allowing the onions to gently soften develops a deeper, sweeter flavor.

5. Add the chopped chard, parsley, salt, and pepper to the skillet with the onions. Cook the mixture, stirring occasionally, for about 5 minutes, allowing the flavors to meld together.

6. Stir in the drained and flaked tuna. Cook the mixture until the tuna is just heated through, about 2-3 minutes. Be careful not to overcook the tuna, as it can become dry and lose its flavor. We want it to be warmed through and integrated with the other ingredients.

7. While the tuna mixture is simmering, bring a large kettle of salted water to a rolling boil. Add the spaghetti and cook until it is al dente, according to package directions. “Al dente” means “to the tooth” in Italian, indicating that the pasta should be firm and slightly resistant when bitten.

8. Drain the spaghetti well, reserving about 1/2 cup of the pasta water. This starchy water can be added back to the sauce if it seems too dry, helping to create a creamy emulsion.

9. In a large bowl, toss the cooked spaghetti with the tuna mixture, the white wine vinegar, and salt and pepper to taste. The vinegar adds a bright acidity that balances the richness of the tuna and olive oil. Add a splash of the reserved pasta water if needed to loosen the sauce and help it cling to the pasta.

10. Just prior to serving, drizzle additional olive oil over the pasta. This adds a final touch of richness and flavor, enhancing the overall sensory experience of the dish. Serve immediately and enjoy!

Expert Tips & Tricks

• Chard Preparation: Thoroughly drying the cooked chard is key to preventing a watery sauce. Use paper towels and gently press out excess moisture.
• Tuna Quality: Opt for high-quality tuna packed in olive oil for the best flavor. The olive oil adds richness to the dish, so don’t discard it!
• Salt the Pasta Water: Salting the pasta water is essential for seasoning the pasta from the inside out. Use about 1 tablespoon of salt per gallon of water.
• Adjust Acidity: The amount of white wine vinegar can be adjusted to your preference. Start with 2 teaspoons and add more if you like a tangier flavor.
• Pasta Water Secret: Reserve pasta water! Adding a little to the sauce helps it cling to the pasta, creating a more cohesive and flavorful dish.

Serving & Storage Suggestions

Serve the Spaghetti con Tonno e Bietolini immediately after preparation for the best flavor and texture. Garnish with a sprinkle of fresh parsley and a drizzle of extra virgin olive oil for an extra touch of elegance. Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently over low heat, adding a splash of water or olive oil if needed to prevent drying. This dish is best enjoyed fresh, as the pasta can become soggy upon reheating.

FAQs (Frequently Asked Questions)

Q: Can I prepare the chard ahead of time?
A: Yes, you can cook and chop the chard up to 2 days in advance and store it in a zip-lock bag in the refrigerator.

Q: Can I use canned tuna in water instead of oil?
A: While you can, the tuna packed in olive oil provides a richer flavor and helps create a more flavorful sauce. If using tuna in water, consider adding an extra tablespoon of olive oil to the skillet when cooking the onions.

Q: How do I prevent the pasta from sticking together after draining?
A: Drain the pasta quickly and toss it immediately with the tuna mixture. The oil in the sauce will help prevent the pasta from sticking.

Q: Can I add other vegetables to this dish?
A: Absolutely! Consider adding sautéed bell peppers, zucchini, or eggplant for a heartier meal.

Q: What is the best way to reheat leftovers?
A: Gently reheat leftovers over low heat on the stovetop, adding a splash of water or olive oil to prevent drying. Avoid microwaving, as it can make the pasta rubbery.
