Crab Macaroni Salad with Old Bay Seasoning is a quintessential dish that brings together the heart of East Coast seafood culture and the nostalgic comfort of creamy pasta salad. Inspired by the breezy boardwalks and summer cookouts along the shores of the Mid-Atlantic—particularly the Chesapeake Bay—this dish captures the essence of seaside indulgence with an unapologetically creamy dressing, tender pasta, and the delicate sweetness of blue crab.
At the core of this salad’s character is Old Bay seasoning, a legendary spice blend created in Baltimore in the 1940s. With its snappy mix of celery salt, paprika, mustard, pepper, and other spices, Old Bay has become deeply entwined with East Coast seafood traditions. It’s a flavor that evokes crab shacks, paper-topped picnic tables, and buttery corn on the cob enjoyed under the sun. In this recipe, Old Bay serves a dual purpose—steeping the dressing with its familiar warmth and providing a bright pop of color and flavor as a final garnish.
The inclusion of lump crab meat takes this salad into luxurious territory. Sweet and briny, the crab creates a light, oceanic contrast to the creamy base of mayonnaise and sour cream. For a leaner version that doesn’t sacrifice richness, Greek yogurt can stand in for some of the sour cream. A small amount of Dijon mustard sharpens the dressing, while lemon juice and zest provide brightness that lifts the dish and prevents it from becoming too heavy.
This salad pays tribute to classic deli-style macaroni salad but elevates it with texture and flavor. Crisp celery, red bell pepper, scallions, and thawed peas offer crunch and color, while finely chopped fresh dill—a typical flavor in both classic crab and pasta dishes—adds grassy depth. A whisper of sweet pickle relish gives that signature tang familiar to American picnic fare, tying everything together with nostalgic ease.
The technique behind this dish is also key to its success. The pasta is cooked just to al dente and then shocked under cold water and air-dried on a sheet pan. This crucial step prevents the creamy dressing from becoming watery and ensures that it clings lovingly to every nook and curve of the macaroni. The salad is then chilled for at least an hour, allowing flavors to meld and making the dish a stress-free make-ahead option for picnics, potlucks, or laid-back lunches.
While this dish is designed to be simple and satisfying, it’s infinitely adaptable. Imitation crab or diced cooked shrimp can stand in for lump crab in a pinch, and gluten-free pasta can be used for dietary needs. Best enjoyed within two days of making and always served cold, this Crab Macaroni Salad with Old Bay seasoning is more than just a pasta salad—it’s a nostalgic celebration of a coastal summer on a plate.

- Chef’s Knife
- Cutting board
- Microplane zester
- Citrus Juicer
Ingredients
- 1 tbsp kosher salt for the pasta water
- 12 oz elbow macaroni dry; about 3 cups
- ½ cup frozen peas thawed slightly; blanch with pasta in last minute
- ¾ cup mayonnaise full-fat for best texture
- ¼ cup sour cream or plain Greek yogurt for a lighter touch
- 1 tbsp Dijon mustard
- 2 tbsp fresh lemon juice freshly squeezed, plus more to taste
- 2 ½ tsp Old Bay seasoning plus extra for garnish
- ½ tsp celery seed optional but classic deli flavor
- ¼ tsp freshly ground black pepper plus more to taste
- 1 tsp lemon zest finely grated on a microplane
- 2 tbsp sweet pickle relish or finely chopped dill pickles, to taste
- 1 cup celery finely diced (about 2 medium stalks)
- ½ cup red bell pepper small dice
- ¼ cup red onion finely minced; rinse briefly if sharp
- 2 tbsp scallions thinly sliced, green parts only
- 2 tbsp fresh dill finely chopped, plus extra for garnish if desired
- 12 oz lump crab meat seafood-quality; picked over for shells; drain well
- ½ tsp kosher salt to season dressing; adjust to taste
- 1 tsp Old Bay seasoning for garnish at serving
- 4 wedges lemon for serving
Instructions
- Boil the Pasta: Bring a large pot of water to a rolling boil (about 4–6 quarts). Season with 1 tbsp kosher salt, then add the elbow macaroni. Cook, stirring occasionally, until just al dente, about 8 minutes. In the final 1 minute, add the peas to blanch.
- Cool and Dry: Drain in a colander and rinse under cold running water until the pasta is cool to the touch, about 1–2 minutes. Shake off excess water, then spread the pasta and peas on a rimmed sheet pan to air-dry for 5 minutes so the dressing clings beautifully.
- Whisk the Dressing: In a large mixing bowl, whisk together mayonnaise, sour cream, Dijon, lemon juice, Old Bay, celery seed, black pepper, lemon zest, and sweet relish until smooth and emulsified, about 30 seconds. Season with 1/2 tsp kosher salt, adjusting to taste.
- Combine and Fold: Add the cooled pasta and peas to the bowl along with celery, red bell pepper, red onion, scallions, and dill. Toss and fold with a rubber spatula until every curve of macaroni is coated and the vegetables are evenly dispersed, about 1–2 minutes.
- Add the Crab: Gently fold in the lump crab meat just until distributed, taking care not to shred the large pieces, about 30–45 seconds. Taste and adjust with more lemon juice, Old Bay, or salt as needed.
- Chill and Serve: Cover and refrigerate at 38–40°F / 3–4°C for at least 60 minutes to let the flavors marry. Before serving, give a gentle stir, dust with the reserved Old Bay, garnish with extra dill, and offer lemon wedges alongside.
Notes
Chef’s Tips:
- Season the water generously—this is your only chance to season the pasta itself; the salad will taste flat otherwise.
- Rinsing and air-drying the pasta prevents a watery dressing and helps it cling for a glossy finish.
- Use lump or jumbo lump crab for the best texture; if using canned, drain well and gently pick through for shells.
- For a lighter dressing, swap half the mayonnaise with Greek yogurt and add an extra teaspoon of lemon juice.
- Make-Ahead: Salad improves after a chill; stir and refresh with a squeeze of lemon and a teaspoon of mayo if it seems dry.
- Substitutions: Imitation crab or chopped cooked shrimp works in a pinch; for gluten-free, use your favorite GF elbow pasta and cook just to al dente.
- Storage: Keep refrigerated at 38–40°F / 3–4°C and enjoy within 2 days for peak flavor and seafood safety.
