Fiery Crockpot Camarones a la Diabla with Charred Corn

This slow cooker camarones a la diablo brings the bold, smoky heat of a Mexican cantina to your kitchen with almost no effort. Jumbo shrimp and sweet charred corn simmer in a fiery guajillo-chipotle butter sauce until the shrimp are juicy and the sauce turns into a glossy, clingy glaze.

Serve it with warm tortillas, creamy avocado, and a generous squeeze of lime. It is the kind of dinner that feels like a celebration, yet comes together from simple pantry staples.

Camarones a la Diabla is a classic Mexican dish known for its fiery red sauce made from dried chilies, tomatoes, and garlic. This version takes a shortcut by using the slow cooker, which lets the flavors meld and deepen while the shrimp cook gently.

The result is a rich, spicy, and slightly smoky sauce that coats every shrimp and corn wheel. Perfect for a weeknight dinner or a festive weekend meal, this recipe is as easy as layering ingredients and letting the Crockpot do the work.

Ingredients

Why this recipe works

The slow cooker is the secret here: it gently poaches the shrimp in the seasoned butter sauce, keeping them tender and preventing them from toughening. The low, steady heat also allows the guajillo and chipotle flavors to infuse into the butter, creating a sauce that is complex and deeply savory. Because the shrimp cook in their own juices, they stay moist and plump, while the corn absorbs the spicy butter and becomes a sweet, smoky counterpoint.

Another reason this method works is the dump-and-go approach. You simply layer the ingredients, set the timer, and walk away. The sauce comes together in minutes, and the slow cooker does the rest. This hands-off technique is ideal for busy home cooks who want a restaurant-quality meal without constant stirring or watching. The final glaze is thick enough to cling to every bite, making each serving as satisfying as the last.

Notes and substitutions

For the best texture, use shell-on jumbo shrimp. The shells protect the meat during the long cook and add extra flavor to the sauce. If you prefer peeled shrimp, reduce the cooking time and check for doneness at 60 minutes.

The corn should be fresh and cut into thick wheels so they hold their shape and char nicely. Roasted tomatoes bring a sweet, slightly charred note; fire-roasted canned tomatoes are a great substitute when fresh are out of season.

Guajillo chili puree is the backbone of the sauce. It is made from dried guajillo chilies that are soaked and blended, and it is available in many Mexican grocery stores or online.

If you cannot find it, you can make your own by soaking dried guajillos in hot water and blending with a little of the soaking liquid. Chipotle peppers in adobo add smoky heat; adjust the amount to your tolerance. The butter and lime juice round out the sauce, balancing the heat with richness and acidity.

• shell-on jumbo shrimp: Peeled and deveined shrimp work, but reduce cook time to 45–60 minutes and check for doneness at 145°F (63°C).
• guajillo chili puree: Use 3 dried guajillo chiles, stemmed, seeded, soaked in hot water for 20 minutes, then blended until smooth.
• roasted tomatoes: Use 1 (14.5-oz) can of fire-roasted diced tomatoes, drained slightly.
• chipotle peppers in adobo: Use 1 tsp smoked paprika plus 1 tsp cayenne for a similar smoky heat, though the flavor will be less complex.
