Ingredients You Need
Seafood
- 1 pound large shrimp, peeled and deveined, tails on or off
- 1 pound fresh mussels, scrubbed and debearded
- 1 teaspoon kosher salt, divided
- 1 teaspoon black pepper, divided
Aromatics and flavor
- 3 tablespoons unsalted butter
- 2 tablespoons olive oil
- 6 cloves garlic, finely minced or pressed
- 1 small shallot, finely minced
- 1 teaspoon crushed red pepper flakes, optional for heat
- Zest of 1 lemon
- Juice of 1 lemon, plus extra wedges for serving
- 2 tablespoons fresh parsley, chopped
- 1 tablespoon fresh basil or chives, chopped, optional
Creamy garlic sauce base
- 1 cup heavy cream
- 1 cup low sodium chicken broth or seafood stock
- 1 teaspoon Dijon mustard (adds depth, does not taste like mustard)
- 1 teaspoon Italian seasoning or dried oregano and thyme mix
- 1 teaspoon paprika or smoked paprika
- 1 tablespoon grated Parmesan or Pecorino Romano, plus more for serving
- 1 teaspoon cornstarch mixed with 1 tablespoon cold water, optional for thicker sauce
Pantry shortcuts and notes
- Use frozen shrimp and frozen mussels if you like; thaw them in the fridge overnight or under cold running water.
- Use jarred minced garlic in water if you feel short on time; use 2 teaspoons instead of fresh cloves.
- Use half and half instead of heavy cream if you prefer a lighter sauce, and add the cornstarch slurry to keep it silky.
- Use pre-grated Parmesan from the refrigerated section; avoid the dry shelf-stable kind since it can make the sauce grainy.
Equipment
- Large wide skillet with lid or a large sauté pan
- Medium bowl for seasoning shrimp
- Colander for rinsing mussels
- Small bowl for cornstarch slurry, if using
- Tongs and a large spoon
- Microplane or fine grater for lemon zest and cheese
Quick Tips & substitutions
- Pat the shrimp very dry so they sear and caramelize instead of steaming.
- Toss the shrimp with salt and pepper right before they hit the pan so they stay juicy.
- Rinse mussels under cold water and discard any that stay open after a firm tap.
- Use seafood stock if you want stronger seafood flavor, or chicken broth for a milder taste.
- Swap heavy cream with coconut cream for a dairy free version and keep the same cooking method.
- Use gluten free stock and skip the cornstarch or use a gluten free thickener if you cook for gluten sensitive guests.
- Add more crushed red pepper flakes at the end if you like a spicy creamy garlic sauce.
- Serve the sauce thinner over rice or thicker over pasta; adjust with a splash of broth or an extra teaspoon of cornstarch slurry.
How to Make Shrimp and Mussels in Creamy Garlic Sauce
Prep the seafood and aromatics
Peel and devein the shrimp if needed, then pat them dry with paper towels. Season the shrimp with half the salt and half the pepper and set them aside. Scrub the mussels under cold water and pull off any beards, then tap open ones and toss any that do not close.
Mince the garlic and shallot, zest the lemon, and chop the parsley. Keep everything close to the stove so you move quickly once the pan heats. This setup keeps the sauce from overcooking while you search for ingredients.
Sear the shrimp
Heat a large skillet over medium high heat and add 1 tablespoon olive oil and 1 tablespoon butter. When the butter foams and smells nutty, add the shrimp in a single layer. Sear the shrimp 1 to 2 minutes per side until they turn pink and opaque at the edges.
Pull the shrimp from the pan and place them on a plate. They will finish cooking gently in the sauce later. Keep the fond on the bottom of the pan since it adds flavor to the creamy garlic sauce.
Steam the mussels
Add another tablespoon of olive oil to the same pan. Add the shallot and cook 1 to 2 minutes until it softens and turns translucent. Stir in half the garlic and cook about 30 seconds until fragrant.
Pour in half the broth and scrape up the browned bits from the bottom of the pan. Add the mussels and cover the pan with a lid. Cook 4 to 6 minutes over medium high heat until the mussels open.
Pull the mussels out with tongs into a bowl and discard any that stay closed. Pour the cooking liquid into a measuring cup and keep it for the sauce. This liquid tastes briny and adds a big punch of seafood flavor.
Build the creamy garlic sauce
Lower the heat to medium and add the remaining butter to the pan. Add the rest of the garlic and cook about 30 seconds, then stir in the paprika, Italian seasoning, and crushed red pepper flakes. Add the Dijon mustard and stir until everything smells toasty and fragrant.
Pour in the reserved mussel liquid and the remaining broth. Simmer 3 to 4 minutes so the flavors concentrate slightly. Stir in the heavy cream and bring the sauce back to a gentle simmer, not a hard boil.
If you want a thicker sauce, stir the cornstarch slurry and drizzle it into the simmering sauce while you stir. Cook 1 to 2 minutes until the sauce coats the back of a spoon. Taste and adjust with the remaining salt and pepper.
Finish with seafood and fresh flavor
Add the seared shrimp and cooked mussels back into the pan. Toss gently so the creamy garlic sauce coats every piece. Simmer 1 to 2 minutes so the shrimp finish cooking and the mussels warm through.
Turn off the heat and stir in lemon zest, lemon juice, and parsley. Sprinkle in the extra Parmesan and give everything one last gentle toss. Taste again and add a pinch of salt or a squeeze of lemon if you want more brightness.
Plate and serve
Spoon the shrimp and mussels in creamy garlic sauce over your base of choice or into shallow bowls. Make sure each bowl gets plenty of sauce and a mix of shrimp and mussels. Garnish with extra herbs, cheese, and lemon wedges.
Serve right away while the sauce stays silky and the seafood tastes tender. I like to keep a spoon on the table just for scooping up extra sauce.
Recipe Variations
- Gluten free: Use gluten free stock, skip any bread sides, and thicken with cornstarch or arrowroot.
- Dairy free: Swap butter with olive oil and use coconut cream or a rich unsweetened oat cream instead of heavy cream.
- Low carb: Serve over zucchini noodles, steamed broccoli, cauliflower rice, or sautéed spinach.
- Extra veggies: Add baby spinach, cherry tomatoes, or sliced mushrooms to the pan right before you add the cream.
- More protein: Add extra shrimp or some scallops and sear them the same way as the shrimp.
- More heat: Add fresh sliced chili or extra crushed red pepper flakes at the end.
Ways to Serve
- Spoon over al dente pasta such as linguine, fettuccine, or spaghetti.
- Serve with crusty bread or garlic bread to soak up the creamy garlic sauce.
- Pair with fluffy white rice, brown rice, or jasmine rice.
- Serve with mashed potatoes or creamy polenta for a cozy bowl.
- Keep it light and serve over sautéed greens or roasted vegetables.
Storage Success
Cool leftovers of shrimp and mussels in creamy garlic sauce to room temperature within 30 minutes, then store them in an airtight container in the fridge for up to 2 days. Reheat gently on the stove over low heat and add a splash of broth or cream so the sauce loosens without breaking. Avoid boiling the sauce again so the shrimp and mussels stay tender. I usually reheat only what I plan to eat, since seafood tastes best when it spends less time in the fridge and on the stove.
Shrimp and Mussels in Creamy Garlic Sauce
Ingredients
Method
- Rinse the mussels under cold water, discarding any that are cracked or remain open when tapped. Pat the shrimp dry with paper towels.
- Heat the olive oil and butter in a large deep skillet or wide pot over medium heat until the butter is melted and foamy.
- Add the minced garlic and cook, stirring frequently, for 30–60 seconds until fragrant but not browned.
- Pour in the white wine, if using, and simmer for 2–3 minutes to reduce slightly and cook off most of the alcohol.
- Stir in the broth, heavy cream, red pepper flakes, paprika, dried thyme, salt, and black pepper. Bring the mixture to a gentle simmer.
- Add the mussels to the pan, cover with a lid, and cook for 4–5 minutes, shaking the pan occasionally, until most mussels have opened.
- Add the shrimp to the pan, re-cover, and cook for another 3–4 minutes, just until the shrimp turn pink and opaque and all mussels that will open have opened. Discard any mussels that stay closed.
- Reduce the heat to low and stir in the Parmesan cheese, if using, along with the lemon juice and chopped parsley. Taste the sauce and adjust seasoning with additional salt and pepper if needed.
- Serve the shrimp and mussels immediately in shallow bowls, spooning plenty of creamy garlic sauce over the top. Accompany with crusty bread for dipping, if desired.
