Make-ahead marinated shrimp appetizer with Dijon, tarragon vinegar, and lemon. Bold flavor that gets better overnight—perfect for parties.
This is the kind of no-stress appetizer that tastes like you did more work than you did. The shrimp is already cooked, the marinade is bold and fresh, and the flavor improves as it chills—so you can prep it ahead, pull it out when guests arrive, and watch it disappear.
Why This Recipe Works
- Cooked shrimp + oil-based marinade means the vinegar and lemon add flavor without “cooking” the shrimp into a tough or mushy texture.
- Warm shrimp absorbs marinade better, faster, so the flavor sinks in where it counts.
- Two vinegars + Dijon build tangy depth, while olive oil smooths and carries the flavors.
- A long marinating window (4–10 hours) makes this ideal for parties, potlucks, and meal prep.
Ingredients (& what they do)
** You can find the full recipe ingredients and instructions on the printable recipe card below.
- Large shrimp, peeled and deveined — Large shrimp stay meaty and tender through a longer marinade.
- Fresh parsley, finely chopped — Adds freshness, color, and a clean herbal top note.
- Green onions, finely chopped — Mild onion flavor that doesn’t overpower the shrimp.
- Tarragon vinegar — The signature “zing” with a subtle herbal edge. If you don’t have tarragon vinegar, swap it for White Wine Vinegar or Apple Cider Vinegar.
- Red wine vinegar — Adds deeper tang and balances the richness of the oil. If you don’t have Red Wine Vinegar, swap it for Sherry vinegar.
- Olive oil — Helps the shrimp marinate for hours without turning tough, and carries flavor evenly.
- Dijon mustard — Adds body and sharpness; helps bind the marinade so it clings. If you don’t have Dijon mustard, swap it for whole-grain mustard.
- Red pepper flakes (more/less to taste) — Gentle heat you can control.
- Salt — Pulls everything together and boosts flavor.
- Fresh lemon juice — Brightens the whole bowl without taking over.
- Ground black pepper, to taste — Adds a mild bite in the background.
How to Make this Make-Ahead Marinated Shrimp Appetizer
** You can find the full recipe ingredients and instructions on the printable recipe card below.
- Cook the shrimp (if needed). Boil shrimp in salted water until pink, about 2 1/2 to 3 minutes. Drain immediately.
- Transfer while warm. Put warm shrimp into a large bowl or zip-top bag.
- Mix the marinade. Combine the remaining ingredients and pour over the shrimp. Toss until every shrimp is coated.
- Chill and marinate. Cover and refrigerate 4 to 10 hours (overnight works very well).
- Serve. Drain excess marinade before serving; serve chilled or at room temp.
Pro Tips
- Do not overcook the shrimp. The moment they turn pink, remove from heat and drain right away.
- Marinate the shrimp while it’s warm for better flavor absorption.
- Do not rinse before serving. Just drain the excess marinade, so you keep the flavor.
- Adjust the heat by adding or removing red pepper flakes.
Recipe Variations
- Extra-spicy: Add additional red pepper flakes or a pinch of cayenne.
- Herb-forward: Add chopped fresh dill or extra parsley for a greener, fresher finish.
- Garlic version: Whisk [paid link] in 1–2 minced garlic cloves for a bolder bite.
- Citrus twist: Add a little lemon zest for a brighter aroma.
- No tarragon vinegar: Swap in white wine vinegar and add a small pinch of dried tarragon (or a splash of tarragon-infused vinegar if you have it).
Serving Suggestions
- Toothpick appetizer platter (classic party setup).
- Spoon over salad greens for a light lunch.
- Serve with crusty bread to soak up the marinade.
- Pair with pasta salad, roasted vegetables, or a simple cucumber-tomato salad.
New Life for Leftovers
- Shrimp salad: Chop and fold into mayo (or Greek yogurt) with celery and extra green onion.
- Wraps: Add to a tortilla or naan with lettuce and sliced tomatoes.
- Rice bowl: Pile over rice with cucumbers and a squeeze of lemon.
Storage
Refrigerator: Store covered in the fridge and keep it cold. For the best texture, eat within 3–4 days (your source post says up to 4 days).
Freezer: Not recommended. Freezing and thawing marinated shrimp can make it watery and softer, and the herbs can darken.
Reheating / serving temp (include this so readers don’t guess)
This recipe is meant to be served cold or at room temperature. If you want it less chilled, let it sit out 10–15 minutes before serving.
Do not microwave (shrimp turns rubbery fast). If someone insists on warm shrimp, the gentlest option is to drain them and warm them very briefly in a skillet just until barely heated—then stop.
People Often Ask (FAQs)
How long should cooked shrimp marinate?

No—just drain the excess marinade.
Can I start with pre-cooked shrimp?
Yes, you can start with pre-cooked shrimp.

Do you know how long this would keep in the refrigerator?
Hi Cheri,
Once cooked and in the marinade, this will last in the fridge covered in a container for up to 4 days. We never really have any last that long. ;)
I’ve eaten up to 2 weeks later. It’s full of vinegar and salt and olive oil which preserve. The marinade is a keeper.
Could precooked shrimp be used instead of cooking fresh?
Yes, you can start with precooked shrimp.
Yes, you can. But the fresher the better.
these are addictive – i suggest to double the recipe. They last in the fridge and it was hard to stop eating them
