This dish is a celebration of fresh coastal ingredients, finished with a touch of heavy cream and bright parsley for a restaurant-quality experience at home.
🥗 Ingredients
The Seafood
- 2 pounds Fresh Mussels (scrubbed and debearded; discard any that are open and won't close)
The Aromatic Base
- 3 tablespoons Unsalted Butter (high-quality European style preferred)
- 2 large Shallots (finely minced)
- 4 cloves Garlic (thinly sliced or minced)
- 3 sprigs Fresh Thyme (leaves removed from stems)
- 1/4 teaspoon Red Pepper Flakes (optional, for a subtle hint of heat)
The Steaming Liquid
- 1 cup Dry White Wine (such as Sauvignon Blanc or Pinot Grigio)
- 1/2 cup Chicken or Seafood Stock (low-sodium)
- 1 tablespoon Lemon Juice (freshly squeezed)
The Finishing Touches
- 1/4 cup Heavy Cream (adds a luxurious silky texture)
- 1/2 cup Fresh Flat-Leaf Parsley (roughly chopped)
- to taste Sea Salt (mussels are naturally salty, so use sparingly)
- 1/2 teaspoon Black Pepper (freshly cracked)
👨🍳 Instructions
-
1
Thoroughly rinse the mussels under cold running water. Use a stiff brush to scrub the shells and pull away the 'beard' (the fuzzy bits) by tugging them toward the hinge of the shell.
-
2
Inspect each mussel; if any are open, tap them against the counter. If they do not close, discard them immediately as they are no longer fresh.
-
3
Set your Instant Pot to the 'Sauté' function on the 'Normal' or 'Medium' setting. Add the butter and allow it to melt until it begins to foam.
-
4
Add the minced shallots to the pot and sauté for 2-3 minutes until they become translucent and fragrant, taking care not to brown them.
-
5
Stir in the garlic, thyme leaves, and red pepper flakes. Cook for just 1 minute more until the garlic is aromatic.
-
6
Pour in the white wine and use a wooden spoon to scrape any flavorful browned bits from the bottom of the pot (deglazing). Let the wine simmer for 2 minutes to cook off the harsh alcohol bite.
-
7
Add the chicken or seafood stock and the lemon juice. Stir to combine the liquid base.
-
8
Gently add the cleaned mussels into the Instant Pot, spreading them out in an even layer. Do not worry if they aren't fully submerged; the steam does the work.
-
9
Secure the lid and set the steam release valve to the 'Sealing' position. Cancel the Sauté function.
-
10
Select 'Manual' or 'Pressure Cook' on High Pressure and set the timer for exactly 1 minute. It will take about 5-8 minutes to come to pressure.
-
11
As soon as the cooking cycle finishes, perform a 'Quick Release' by carefully moving the valve to the 'Venting' position. Avoid a natural release, as this will overcook the delicate seafood.
-
12
Once the pin drops, open the lid. Use a slotted spoon to transfer the opened mussels to a large serving bowl. Discard any mussels that remained closed after cooking.
-
13
Switch the Instant Pot back to 'Sauté'. Stir in the heavy cream and half of the parsley. Let the sauce simmer for 2 minutes to thicken slightly.
-
14
Taste the broth and season with salt and pepper if needed. Pour the hot, creamy broth over the mussels in the bowl.
-
15
Garnish with the remaining fresh parsley and serve immediately while steaming hot.
💡 Chef's Tips
Always buy mussels the same day you plan to cook them for the best flavor and safety. Never overcook mussels; they should be plump and tender, not rubbery—the 1-minute pressure setting is precise for this reason. If you don't cook with wine, substitute with extra seafood stock and an additional squeeze of lemon for acidity. Ensure you 'debeard' the mussels properly, as the beards are tough and unpleasant to eat. Use a high-quality butter; since there are so few ingredients, the quality of the fat significantly impacts the sauce flavor.
🍽️ Serving Suggestions
Serve with a warm, crusty French baguette to soak up every drop of the garlic-wine broth. Pair with a chilled glass of the same white wine used in the recipe, like a crisp Muscadet or Sauvignon Blanc. Accompany with a side of 'Frites' (French fries) and a dollop of garlic aioli for a classic Belgian-style meal. A simple green salad with a sharp Dijon vinaigrette provides a refreshing contrast to the rich, buttery sauce. Offer an extra bowl on the table for guests to discard their empty shells.
