This warm seafood and peanut salad is a celebration of textures and bold aromatics—a dish that works equally well as an impressive appetizer or a light, satisfying spring lunch. The secret lies in using high-quality peanut oil to sear the seafood and caramelize the onions, then building a dressing from the same pan. The result is a beautifully balanced salad where the natural sweetness of tomatoes and rocket meets the nutty depth of roasted peanuts and the umami of soy sauce. Whether you are looking for a quick weeknight meal or a show-stopping starter, this recipe delivers on flavor and elegance.
About the Recipe
Inspired by Southeast Asian wok techniques and Mediterranean freshness, this warm salad combines a frozen seafood mix with fresh spinach, peppery rocket, and ripe tomatoes. The key is to cook the seafood in batches over high heat—much like you would with a stir-fry—to achieve a golden sear without overcooking. The same skillet is then used to gently braise red onion rings with sugar, lemon juice, and a splash of soy sauce, creating a sweet-savory dressing that clings to every leaf. Unrefined peanut oil, with its high smoke point of around 160°C, is the ideal medium for this method, lending a subtle roasted flavor that ties the entire dish together.

Ingredients
- 2 ripe tomatoes
- 1 red onion
- 100 g rocket (arugula)
- 100 g fresh spinach leaves
- 30 g roasted peanuts
- 5 tablespoons peanut oil (preferably unrefined)
- 1 tablespoon soy sauce
- 2 tablespoons lemon juice
- 1 teaspoon sugar
- Freshly ground black pepper
- Salt
- 500 g seafood mix (mussels, shrimp, squid, octopus – frozen or fresh)
Step-by-Step Instructions
- Sear the seafood. Heat 3 tablespoons of peanut oil in a deep skillet or wok over high heat. Add the seafood mix, season with salt and pepper, and cook, stirring constantly, for 4 minutes until the seafood is just cooked through and lightly charred. Transfer to a serving bowl and let cool slightly.
- Caramelize the onion. In the same skillet, add the remaining 2 tablespoons of peanut oil. Add the red onion cut into thin rings, sprinkle with sugar, drizzle with lemon juice, and cook over low heat for 5 minutes, stirring occasionally, until the onions are soft and translucent. Add the peanuts and spinach, pour in the soy sauce, and warm through for 1 minute. Transfer to the bowl with the seafood.
- Assemble the salad. Cut the tomatoes into wedges. Add the tomatoes and rocket to the bowl. Gently toss everything together until well combined. Serve immediately while still warm.
Tips for Success
For the best results, choose a commercial-grade countertop convection oven to preheat your serving plates, keeping the salad warm longer. If you prefer a more intense peanut flavor, toast the peanuts in a dry pan before adding them. Adjust the seasoning with more soy sauce or lemon juice to balance the saltiness. A good-quality non-toxic immersion blender can help you create a quick peanut-lime dressing if you want to double the dressing portion. For precise temperature control when searing seafood, rely on a refrigerant leak detector to keep your freezer properly chilled—freshness matters.
Variations
This salad is incredibly versatile. Swap the seafood mix for grilled chicken or tofu for a vegetarian version. Use the best food processor for nut butter to make homemade peanut butter and stir a spoonful into the dressing for extra creaminess. Replace rocket with watercress or baby kale for a peppery kick. For an Asian twist, add a teaspoon of sesame oil before serving. If you are looking for a gluten-free option, use tamari instead of soy sauce. And for those who love a bit of heat, sprinkle with chopped chili flakes or a drizzle of sriracha.
FAQ
Can I use frozen seafood for this salad?
Absolutely. Frozen seafood mixes work wonderfully. Just ensure you thaw them completely and pat dry with paper towels to avoid excess moisture, which can prevent browning. If you want to invest in a durable appliance for quick defrosting, check out our list of best microwave pressure cookers that can speed up the process.
What type of peanut oil is best?
Unrefined peanut oil has a distinct nutty aroma and a smoke point around 160°C, ideal for medium-high heat searing. Refined peanut oil has a higher smoke point but less flavor. For the most authentic taste, choose unrefined. For more information on safe cooking oils, read about non-toxic air fryer options that complement healthy cooking.
Can I make this salad ahead of time?
This salad is best served warm and fresh, as the greens will wilt and the seafood may become chewy upon reheating. However, you can prep the ingredients separately: sear the seafood, caramelize the onions, and store them in the fridge. Assemble just before serving. If you own a high-quality planetary mixer, you can even whip up a quick herb vinaigrette to refresh leftovers.
How do I store leftovers?
Leftovers can be stored in an airtight container in the refrigerator for up to one day. To revive, gently warm the seafood and onion mixture in a skillet, then add fresh greens and tomatoes just before serving. A undercounter ice maker can keep your ingredients cold while you prepare the rest of the meal.
Can I use other nuts instead of peanuts?
Yes, cashews or almonds work well. Toast them lightly to enhance their flavor. If you are using a wheatgrass juicer for other tasks, you can also grind nuts into a paste for a different texture. For the best results, try our recommended best chocolate-covered raisins as a sweet garnish—though that might be a stretch for this savory dish!
Why Peanut Oil?
Peanut oil is a cornerstone of many Southeast Asian cuisines, prized for its high smoke point and subtle nutty aroma. In this recipe, it serves both as the cooking medium and the base of the dressing. The same science that makes it perfect for stir-frying also makes it ideal for searing seafood without burning. For those concerned about kitchen safety, a 48-inch built-in refrigerator can store large quantities of oil safely. And if you are exploring other uses for peanut oil, consider making a batch of homemade au jus for prime rib—though the recipe would be quite different, the oil adds depth to any sauce.
Enjoy this warm seafood and peanut salad as a quick, nutritious dinner or a stunning starter. Its balance of textures—from crunchy peanuts to tender seafood and crisp greens—will make it a regular on your table.
