Ingredients
White Crab Meat - The star of the dish, crab meat, brings a sweet, delicate flavor that pairs perfectly with the robust, spicy sauce. I love using fresh, ready to eat crab meat or high-quality canned crab because it ensures that the natural sweetness of the crab shines through.
Bucatini or Spaghetti - These pasta shapes are ideal for this dish because their long strands hold the luscious sauce beautifully. Bucatini, with its hollow center, adds an extra element of texture.
Garlic and Shallots - Garlic and shallots are the foundation of this sauce. Slow-cooked shallots add a caramelized sweetness that balances the heat of the chilli, while garlic adds depth and a touch of pungency.
Olive Oil - Good olive oil is essential in Italian-inspired cooking. It not only enhances the overall flavor but also provides a rich base for the shallots and garlic to cook in.
Tomato Paste - Tomato paste gives the sauce its deep, rich flavor and vibrant color. I prefer using tomato paste because it intensifies the tomato flavor without adding excess liquid.
Chilli and Chilli Flakes - These bring the heat, transforming a simple tomato sauce into a bold, spicy base for the crab pasta. I like to use a combination of fresh red chilli for brightness and chilli flakes for a deeper, warming spice.
Olives - Chopped olives add a briny, salty kick that complements the sweetness of the crab and the richness of the sauce.
Flat leaf parsley - Fresh parsley adds a burst of freshness and a subtle herbal note that ties the whole dish together.
Sea Salt and Black Pepper: Seasoning is everything in this dish. A pinch of sea salt enhances the flavors, while freshly cracked black pepper adds a touch of earthiness.

Instructions
- Step 1: Begin by slicing your shallots and each garlic clove thinly and finely chopping the red chilli. Heat olive oil in a large pan over medium heat. Add the shallots, garlic, and chilli, along with a generous pinch of sea salt and black pepper. Reduce the heat to medium-low and stir occasionally, allowing the shallots to caramelize. This step takes about 25–30 minutes but is key to developing the deep, sweet base for your chilli tomato crab pasta.
- Step 2: About 15 minutes into the shallots caramelizing, bring a large pot of salted water to a boil and cook your bucatini or spaghetti until al dente. Reserve a cup of the starchy pasta water before draining. Once the shallots are golden and soft, lower the heat and stir in the tomato paste. Cook for 2–3 minutes until the paste deepens in color, enhancing its rich, concentrated flavor.
- Step 3: Turn the heat under the pan back to medium and add the drained pasta to the sauce. Gradually pour in some reserved pasta water, tossing the pasta to create a glossy, well-coated consistency. Adjust the amount of water to your liking.
- Step 4: Add the white crab meat, chopped olives, chilli flakes, and parsley to the pan. Gently toss everything together, ensuring the crab is evenly distributed without breaking it apart too much. Taste and adjust seasoning with more salt and pepper if needed.
5: Step 5: Plate your chilli tomato crab pasta, garnishing with a sprinkle of fresh parsley for a pop of color and freshness. Serve immediately and savor every bite of this spicy, seafood-packed delight.
Hint: Don’t overcook the crab; it’s already cooked and just needs to be gently warmed through to retain its delicate texture.
Substitutions for Chilli Tomato Crab Pasta
White Crab Meat - Substitute cooked shrimp, lobster meat, or even canned tuna for the crab. Shrimp or lobster will keep the seafood flavor intact, while tuna provides a more budget-friendly option with a slightly firmer texture.
Bucatini or Spaghetti - Replace with linguine, fettuccine, or even penne if you prefer shorter pasta. If you’re looking for a gluten-free option, try gluten-free spaghetti or zoodles (zucchini noodles). Any type of pasta and dry pasta will work here.
Garlic - Use garlic powder if fresh garlic isn’t available, or substitute with shallots for a milder flavor. Roasted garlic can also be used for a sweeter, richer taste.
Shallots - Substitute with red onion or yellow onion if you can’t find shallots. They provide a similar sweetness, though the flavor will be slightly less delicate.
Olive Oil - Replace with avocado oil or vegetable oil for a neutral alternative. For a slightly nutty flavor, you could use sesame oil, though it will add an Asian-inspired twist.
Sea Salt and Black Pepper - Use kosher salt or table salt for the sea salt and white pepper or crushed red pepper as substitutes for black pepper. Adjust to taste as needed.
Tomato Paste - Swap with tomato purée or crushed tomatoes, reducing the liquid slightly to maintain the thick consistency. Sun-dried tomato paste can add a deeper, richer flavor as well.
Olives - Use capers for a similar briny flavor, or try artichoke hearts for a unique twist. If you don’t like olives, leave them out and add a pinch of extra salt to compensate.
Red Chilli - Substitute with jalapeño, serrano pepper, or a dash of cayenne pepper for heat. For a milder kick, try sweet red peppers or a small amount of smoked paprika.
Chilli Flakes - Replace with red pepper flakes, Aleppo pepper, or even a splash of hot sauce for a spicy boost. Adjust based on your spice tolerance.
Parsley - Use basil, cilantro, or chives for a fresh herbal element. For a less traditional take, you could also use arugula or spinach, finely chopped.
Variations
Chilli Prawn Pasta - Swap the fresh crab meat for prawns, cooking them in the sauce until tender for a heartier twist. Also add anchovies to the sauce for an umami depth.
Vegetarian Version - Use roasted cherry tomatoes and capers instead of crab for a flavorful meat-free option.
Lemon Herb Crab Pasta - Add lemon zest, lemon juice, white wine and fresh dill to the sauce for a bright, zesty variation of this chilli crab pasta.
Equipment
Large skillet or shallow cast iron
Storage
If you have leftovers, store the chilli tomato crab pasta in an airtight container in the refrigerator for up to 2 days. Reheat gently in a pan over low heat, adding a splash of water or olive oil to loosen the sauce as needed. Freezing is not recommended, as the crab can become tough and lose its flavor. If you plan to meal prep, make the sauce ahead and store it separately from the pasta. The sauce can be refrigerated for up to 4 days. Cook the pasta fresh when ready to serve, and toss it with the reheated sauce and crab for the best texture and taste.
Top Tip
Reserve your pasta water—it’s packed with starch, which helps the sauce cling to the pasta and creates that glossy finish to the chilli tomato crab pasta.
FAQ
Freezing crab pasta isn’t ideal, as crab can become rubbery and lose its delicate flavor. If necessary, freeze the sauce separately for up to 1 month and cook fresh pasta when serving. Thaw and reheat the sauce gently to preserve the crab’s texture.
Serve chilli crab with crusty bread, steamed rice, or noodles to soak up the spicy sauce. Alternatively, pair it with simple sides like a fresh cucumber salad or stir-fried greens for a balanced meal.
