  Amount  Measure       Ingredient -- Preparation Method
--------  ------------  --------------------------------
  8             ounces  linguine
                        Kosher salt
  4        tablespoons  unsalted butter -- divided
  2        tablespoons  olive oil -- divided
  1/4           cup  minced shallots
  1           teaspoon  minced garlic
  2                     Fresno chiles -- red jalapeños, or red Thai chiles, seeded, sliced into thin rounds
  1 1/2    tablespoons  fresh lemon juice -- (or more) divided, plus 2 teaspoons (packed) finely grated lemon      zest, divided
                        Freshly ground black pepper
  8             ounces  cooked shelled Dungeness crab, king crab, or jumbo lump crabmeat, picked over for shells
  1/3           cup  fresh mint leaves -- gently torn, divided

Cook pasta in a large pot of boiling salted water, stirring occasionally, until al dente. Drain, reserving 1 cup pasta cooking liquid.
Meanwhile, melt 1 Tbsp. butter with 1 Tbsp. olive oil in a large skillet over medium heat. Add shallots and stir until just soft, 3–4 minutes. Add garlic and 1 chile and cook, stirring often, until fragrant, about 1 minute.
Add 1/2 Tbsp. lemon juice and 3 Tbsp. pasta cooking liquid to shallot mixture; add a pinch of pepper. Stir until liquid is almost evaporated, about 1 minute.
Transfer pasta to skillet and add 1/2 cup reserved pasta cooking liquid. Increase heat to medium-high.
Cook, tossing pasta or stirring with tongs, until liquid is almost evaporated and pasta becomes glossy, about 2 minutes. Add the remaining 3 Tbsp. butter, 1 Tbsp. oil, 1 Tbsp. lemon juice, 1 tsp. lemon zest, crab, half of mint, and more chile rounds, if desired.
Stir pasta until butter melts and pasta is well coated, adding more pasta cooking liquid if dry. Divide between bowls; top with remaining 1 tsp. lemon zest and mint. Sprinkle with more lemon juice if desired.
