Crab and Asparagus Soup | Keto, Low-Carb & Diabetic-Friendly
Ingredients
- 12 oz lump crab meat fresh or quality canned, drained and checked for shells
- 1 lb fresh asparagus woody ends trimmed, cut into 1-inch diagonal pieces
- 2 tablespoons fresh ginger peeled and finely grated or sliced
- 6 cups low-sodium chicken or seafood broth vegetable broth works too
- 1 teaspoon sea salt or to taste
- 1 teaspoon black pepper freshly ground
- 2 tablespoons fresh lemon juice or 2 tablespoons dry white wine, optional for brightness
- 2 tablespoons coconut cream optional, for dairy-free creaminess
- 2 tablespoons Greek yogurt optional, if dairy is tolerated (adds 2g carbs per serving)
- 2 tablespoons green onions thinly sliced, for garnish
- 2 tablespoons fresh cilantro chopped, for garnish
- 1 teaspoon sesame oil for drizzling, optional
Equipment
- 1 Large pot or Dutch oven
- 1 Sharp Knife
- 1 Spoon for peeling ginger
- 1 Ladle
- 1 Strainer (if using woody asparagus ends)
Method
- Trim the woody ends from the asparagus stalks and cut the tender parts into 1-inch diagonal pieces. Reserve the woody ends if you want extra flavor in your broth (you’ll strain them out later).
- Peel the fresh ginger using the edge of a spoon to easily scrape away the skin. Finely grate or thinly slice the ginger, depending on your preference for intensity.
- Pour the broth into a large pot. If using reserved woody asparagus ends, add them now. Bring the broth to a gentle simmer over medium heat and let it bubble for 3-4 minutes to infuse flavor. Strain out and discard the woody ends if used.
- Add the prepared ginger to the simmering broth and cook for 2-3 minutes, stirring occasionally, to infuse the soup with warming ginger flavor.
- Add the asparagus pieces to the pot and simmer for 4-5 minutes until they’re crisp-tender but still bright green. Don’t overcook—they should have a slight bite.
- Reduce heat to low. Gently fold in the crab meat and warm through for 1-2 minutes only. Avoid boiling vigorously or the crab will become rubbery and tough.
- Season the soup with salt and pepper to taste. Add a splash of lemon juice or white wine if using, stirring gently to brighten the flavors.
- If desired for creaminess, stir in coconut cream or Greek yogurt just before serving. Remove from heat immediately after adding to prevent curdling.
- Ladle the soup into bowls and garnish with sliced green onions, fresh cilantro, and a light drizzle of sesame oil if desired. Serve immediately while hot.

Let us know how it was!Chef’s Tips for Perfect Crab Asparagus Soup
Crab Selection: Look for lump or jumbo lump crab meat for the best texture and sweetness. Canned crab works in a pinch—just drain it well and check for any shell fragments.
Asparagus Texture: Cut asparagus into 1-inch diagonal pieces for an elegant presentation. Save the woody ends to simmer in your broth for extra flavor, then strain them out before serving.
Ginger Magic: Fresh ginger is key here. Use a spoon to scrape off the skin (it comes right off!) rather than a peeler—you’ll waste less of this precious ingredient.
Broth Boost: For extra depth, add a splash of dry white wine or a squeeze of fresh lemon juice at the end. The acidity brightens all the flavors beautifully.
Make it Creamy: Want a richer soup without added carbs? Stir in 2-3 tablespoons of coconut cream or a dollop of Greek yogurt (if dairy is okay for you) just before serving. This adds about 1-2g carbs per serving.
