Spicy Crab Over Pasta

This spicy crab pasta comes together faster than the water takes to boil for the noodles. Garlic, green bell pepper, and red pepper flakes hit hot olive oil first, then hand-crushed canned tomatoes, fish stock, and tomato paste simmer down into a thick, punchy sauce in under 10 minutes.

The crab meat goes in at the very end and only simmers for a few minutes. Crab is already cooked, so it just needs to warm through and absorb the spicy tomato flavors. Overcook it and the delicate flakes turn rubbery and tough.

Lemon zest is the sleeper ingredient here. It brightens the whole sauce and lifts the crab flavor without adding any liquid acidity. Fish stock instead of chicken stock keeps everything tasting like the sea rather than a barnyard.

Toss it over spaghetti, linguine, or fettuccine and you’ve got a weeknight dinner that tastes like it came from a coastal Italian kitchen.

Kitchen Tips

• Crush the whole canned tomatoes by hand as you add them. It’s faster than chopping and gives you a mix of chunky and smooth textures in the sauce.
• Use double-concentrated tomato paste if you can find it. It adds deeper tomato flavor without extra liquid.
• Don’t stir the crab aggressively once it’s in the sauce. Gentle folding keeps the lumps intact instead of shredding them into threads.
• Save a cup of pasta cooking water. A splash loosens the sauce if it thickens too much when tossed with the noodles.

Variations

• Use shrimp or lobster meat instead of crab for a different shellfish flavor.
• Add a splash of white wine to the sauce when the garlic sizzles for extra depth.
• Swap green bell pepper for roasted red peppers for a sweeter, smokier note.
