Grilled shrimp piled on filet mignon with buttery lobster sauce always steals the show when I want to celebrate. It feels fancy, wows everyone, and my friends won't stop chatting about it after. That creamy lobster blend with perfect steak and seafood sticks in your memory.
One night I couldn’t get us a reservation for our anniversary, so I whipped this up at home. It totally saved the vibe. Now it’s our go-to whenever we want to celebrate something big.
Irresistible Ingredients
- Lemon juice: brightens up the sauce and makes flavors pop
- Lobster bisque: creamy store-bought or homemade soup becomes the base for your sauce
- Olive oil: locks in moisture for shrimp and adds that golden crisp
- Filet mignon steaks: pick ones with lots of marbling—they’re more tender and juicy
- Salt and pepper: you can’t skip these—crust needs that punch
- Shrimp: go for plump, peeled, deveined ones for best bites
- Fresh parsley for garnish: slice or tear for a green, fresh finish
Super Simple Steps
- Ready Your Plates:
- Lay out your serving dishes so you’re not scrambling later. Warm them if you like your food to stay hot.
- Assemble and Enjoy:
- Fan out sliced steak on each plate, add those grilled shrimp right on top, pour over lobster sauce, toss on fresh parsley, and serve right away.
- Let Steaks Rest and Slice:
- Give the steaks a few minutes on a cutting board. Let those juices settle back in, then slice thin across the graining for tender bites.
- Heat Lobster Bisque with Lemon:
- Pour bisque into a saucepan, add lemon juice, and gently warm on low. Don’t let it get too hot or it’ll lose that silky feel.
- Grill and Prep Shrimp:
- When the steak’s halfway done, mix shrimp with oil, salt, and pepper. Grill for just a couple minutes each side till they curl up and turn pink.
- Sear the Filet:
- Drop steaks on your hot skillet with olive oil shimmering. Sear each side four to five minutes. Flip once when the crust looks rich and brown. Check doneness with a thermometer if you want it perfect.
- Season Your Beef:
- Rub each steak all around with salt and pepper, really pressing so it sticks nice and even.
- Fire Up the Grill:
- Turn your grill to medium-high and get it hot before you toss on those shrimp. You want clear grill marks.

Parsley is my go-to here. Makes your plate look pretty and adds fresh flavor. I’ll never forget making this for my parents’ golden anniversary—everyone laughing and the smell of steak and seafood drifting through the kitchen.
Leftover Storing
Let leftovers cool, pack steak and shrimp in separate containers from the sauce. Airtight is best. They’ll keep in the fridge up to two days. When warming up, go gently so shrimp and steak stay tender and sauce doesn’t split.
Swap Suggestions
No filet? Thick sirloin or ribeye does the trick. Any creamy seafood bisque stands in for lobster if needed. Out of lemon? Squeeze in lime instead. For herbs, chives or tarragon offer a fresh bite if you’re out of parsley.

Fun Serving Ideas
Try it with garlicky mashed potatoes or roasted asparagus. Sip a cold glass of rosé or a crisp chardonnay—the brightness pairs so well. Add a lemon wedge for an extra pop of flavor at the table.
Food Traditions
Surf and turf is a classic for big celebrations in the US. Steak with seafood is all about living it up with the best of the land and the ocean. Making it at home means any night can feel special.
Common Recipe Questions
- → What's the best way to tell if the filet mignon is done just right?
Just grab a meat thermometer. Shoot for 125°F for rare, 135°F for medium rare, or 145°F for medium. Let them chill a bit before you slice in.
- → Can frozen shrimp work for this?
Go for it! Thaw them all the way and pat them dry. That way they grill up just right.
- → What can I serve on the side?
Try garlic mashed potatoes, some roasted veggies, or something light like a crisp salad to balance things out.
- → Can the lobster sauce be made ahead?
Totally. Heat it up before you start, then just warm gently before you serve. Super handy if you're short on time.
- → Do I have to grill both the steak and the shrimp?
You sure can. Pop both right on the grill, just tweak the time so nothing overcooks—use a high flame for good sear.
