Clams Posillipo

Recipe Image 10

This recipe is basically the Italian equivalent of a warm hug from your nonna, except she’s also secretly showing off her cooking skills to make everyone else jealous.

Picture this: tender littleneck clams swimming in a robust marinara sauce that’s been elevated with ‘nduja’s spicy kick and anchovy depth, all served over garlic-rubbed rustic bread that soaks up every drop of that liquid gold.

The beauty of Clams Posillipo lies in its deceptive simplicity – you’re essentially creating restaurant-quality Italian coastal cuisine in about 30 minutes flat, using ingredients that don’t require a second mortgage.

That moment when you lift the lid and see all those clams perfectly opened, releasing their briny essence into the already aromatic sauce, is pure kitchen magic that never gets old.

The combination of extra virgin olive oil, white wine, and fresh clam stock creates a base so flavorful that you’ll be tempted to drink it straight from the pan (we won’t judge).

This is the kind of dish that transforms a regular Tuesday into an Italian seaside dinner party, complete with the satisfied sighs and requests for the recipe.

Ingredients

For the Clam Base

60 ml (¼ cup) Stefano extra virgin olive oil, divided
2 garlic cloves, crushed
2 anchovy fillets
15 ml (1 tbsp) ‘nduja
24 littleneck clams, washed and scrubbed

For the Sauce

60 ml (¼ cup) white wine
125 ml (½ cup) clam stock
250 ml (1 cup) Stefano marinara sauce

For the Garlic Bread

2 slices rustic bread
1 garlic clove, peeled

For Garnish

30 ml (2 tbsp) Italian parsley, chopped
1 lemon, zested

Instructions

Prepare the Aromatic Base

1 Heat 30 ml (half) of the extra virgin olive oil in a large frying pan over medium heat. The oil should shimmer but not smoke – this gentle temperature allows the garlic to release its flavor without burning.
2 Add the crushed garlic cloves and cook for 1 to 2 minutes, stirring gently until fragrant. The garlic should turn golden but not brown, as burnt garlic will make the entire dish bitter.
3 Incorporate the anchovy fillets and ‘nduja, cooking for 2 to 3 minutes while stirring. The anchovies should completely melt into the oil, creating a rich umami base, while the ‘nduja releases its spicy oils and becomes fragrant.

Cook the Clams

4 Add the cleaned clams and white wine to the pan. The wine will immediately start to steam and bubble – this is exactly what you want. Cook for 1 to 2 minutes to allow the alcohol to reduce slightly.
5 Pour in the clam stock and marinara sauce, then cover the pan immediately. Cook for 5 to 7 minutes, or until the clams open completely. The steam created will help the clams open while the sauce reduces and concentrates. Discard any clams that remain stubbornly closed after this time.

Prepare the Garlic Bread

6 Meanwhile, heat the remaining 30 ml of olive oil in a large cast iron skillet over medium-high heat until it shimmers. The high heat is crucial for achieving that perfect golden crust on the bread.
7 Pan sear the bread slices until crunchy and golden brown on both sides, about 2-3 minutes per side. The bread should sound hollow when tapped and have a deep golden color.
8 Cut the peeled garlic clove in half and immediately rub it over one side of each hot toasted bread slice. The heat from the bread will release the garlic oils, creating an aromatic base for the clams.

Final Assembly

9 Place the garlic-rubbed bread slices on a serving platter and immediately top with the hot clams and sauce. The bread will absorb some of the flavorful liquid while maintaining its texture. Garnish generously with fresh Italian parsley and bright lemon zest before serving.

Perfect Pairing Suggestions

Beverage Pairings

The bright acidity and seafood richness of Clams Posillipo pairs beautifully with crisp white wines like the recommended Catarratto, Pinot Grigio, or Vermentino. For beer lovers, a light lager or wheat beer complements the briny flavors without overwhelming the delicate clam taste. Non-alcoholic options include sparkling water with lemon, Italian sodas, or a refreshing cucumber mint water that cleanses the palate between bites.

Side Dish Recommendations

Arugula salad with lemon vinaigrette provides peppery contrast to the rich sauce, while roasted fennel with olive oil enhances the Mediterranean theme. Garlic-roasted asparagus adds color and crunch, and creamy polenta serves as an excellent base for soaking up extra sauce. For a lighter option, grilled zucchini ribbons with fresh herbs complement without competing.

Complete Meal Ideas

Start with antipasto featuring olives, roasted peppers, and fresh mozzarella. Follow the clams with a simple lemon granita or panna cotta for dessert. For entertaining, serve alongside linguine alle vongole for guests who prefer pasta, creating an Italian seafood feast. Focaccia bread with herbs makes an excellent appetizer while the clams cook.

Occasion Suggestions

Perfect for romantic dinners, casual entertaining, or summer patio meals. The quick cooking time makes it ideal for weeknight dinners when you want something special without extensive prep. Excellent for wine tasting parties or Italian-themed gatherings.

Pro Tips and Troubleshooting

Professional Techniques

Always purge clams in salt water for 30 minutes before cooking to remove sand and grit. Test each clam by tapping – they should close tightly when handled. Reserve pasta water if serving over linguine, as the starch helps bind the sauce. Warm your serving plates in a low oven to keep the dish hot longer.

Common Mistake Prevention

Never force open stubborn clams – they’re likely dead and unsafe to eat. Don’t overcook opened clams, as they become rubbery quickly. Avoid high heat when sautéing garlic and anchovies, which can turn bitter. Don’t skip the wine reduction step, as raw alcohol will overpower the delicate clam flavor.

Storage and Reheating

Fresh clams are best consumed immediately, but leftover sauce keeps 2-3 days refrigerated. Reheat gently over low heat, adding a splash of clam stock if needed. Never refreeze previously frozen clams. Store unopened clams in the refrigerator covered with damp paper towels, not sealed in plastic.

Make-Ahead Strategies

Prepare the aromatics (garlic, anchovy, ‘nduja base) up to 4 hours ahead and refrigerate. Clean clams the morning of cooking. Toast bread can be done 2 hours ahead and rewarmed briefly. Scale recipe easily – just maintain the oil-to-liquid ratios for best results.

This Clams Posillipo represents everything beautiful about Italian coastal cooking – simple ingredients transformed into something extraordinary through technique and timing. The combination of briny clams, spicy ‘nduja, and aromatic garlic creates layers of flavor that transport you straight to the Italian seaside, proving that the best recipes often require nothing more than quality ingredients and a little patience.
