Blackened Steak & Shrimp

Recipe Note

Recipe FAQ

What makes a blackening crust different from a regular sear?

Blackening is a specific technique developed by Chef Paul Prudhomme in Louisiana: protein is brushed with butter, coated in a spice blend heavy on paprika, cayenne, garlic, and herbs, then cooked in an extremely hot dry pan or griddle. The butter browns and the spices char slightly, forming a dark, intensely flavored crust with a smoky, slightly bitter edge that contrasts with the juicy interior. A regular sear uses high heat to develop Maillard browning in the meat itself; blackening develops browning primarily in the spice-and-butter coating rather than the protein surface. The result is a more aggressively flavored, darker crust than a standard sear produces.

Why marinate the shrimp in Smoke on Wheels BBQ Marinade before adding Cajun seasoning?

The Smoke on Wheels BBQ Marinade is a liquid marinade with a savory, slightly sweet backbone — it seasons the shrimp from the inside and provides a thin coating that helps the Cajun Fusion seasoning adhere evenly to the surface. Shrimp has very little fat to carry seasoning on its own, so the marinade layer functions as both a flavor base and an adhesion agent. Keep the marinate brief — 30–60 minutes maximum for shrimp. Longer and the acid in the marinade begins to denature the proteins, affecting texture.

Why use Parmigiano Reggiano rinds in the gumbo broth?

Parmesan rinds are the outer dried rind of an aged wheel — intensely concentrated in the same glutamates and amino acids that make the cheese savory. Simmered for an hour, they release those compounds into the broth without melting in, adding a depth of umami that chicken stock alone doesn't produce. This is the same technique professional kitchens use to deepen minestrone, tomato sauce, and risotto. Remove them before serving — they don't dissolve and the rind texture itself is unpleasant to eat. Any Parmigiano Reggiano rind works; save them in the freezer until you have enough.

Why does risotto require constant stirring, and what happens if I stop?

Stirring risotto serves two purposes simultaneously: it prevents the rice from sticking to the pan, and — more importantly — it agitates the starch on the outside of each arborio grain, releasing it into the liquid. That released starch creates the characteristic creamy, sauce-like consistency of properly made risotto rather than a pot of cooked rice sitting in broth. If you walk away, the rice sticks, the starch settles, and you lose the emulsified texture. Adding the broth one ladle at a time, allowing each addition to absorb before adding more, builds texture gradually rather than all at once.

Can I cook this Indoors?

We rate this a 3 out of 5 for cooking indoors. Works indoors with adjustments, but the grill is recommended. The gumbo risotto and Cajun Alfredo are fully stovetop components. The blackening step is the challenge — a cast iron skillet on a very high burner can produce the crust, but the spice and butter smoke heavily at blackening temperatures, which requires serious kitchen ventilation. The YS640s griddle's large flat surface handles both the steak and shrimp simultaneously in a way a home skillet can't easily replicate. Do this one outdoors if you can.

Recipe Highlights & Insights

• This is the most complex recipe from the September 26 cooking class — it has three distinct components (steak and shrimp, gumbo risotto, Cajun Alfredo) that each require active attention and come together at plating. The practical strategy for managing this at home is to make the gumbo broth and Cajun Alfredo first, keep them warm, and cook the risotto while the steak and shrimp are marinating. The proteins go on the griddle last and cook fastest — the steak takes 3–4 minutes per side, the shrimp 1–2 minutes. Everything else should be resting and warm before the griddle gets hot.

   

• Clarified butter is specified for searing the steak for a specific reason: regular whole butter contains milk solids that burn at blackening temperatures (which can reach 500°F+), producing acrid, bitter flavors rather than the clean, browned-butter char the crust needs. Clarified butter has the milk solids removed, giving it a much higher smoke point that allows it to withstand griddle temperatures without burning. Ghee is an acceptable substitute; neutral high-smoke-point oils (avocado, refined coconut) also work but don't contribute the butter flavor the crust benefits from.

   

• The Cajun Alfredo sauce is the dish's most versatile component — it's a rich, cheese-spiked cream sauce seasoned with Cattleman's Grill Blackening Seasoning and hot sauce that stands alone as a pasta sauce or a dipping sauce for grilled bread. It reheats well over low heat with a splash of cream stirred in to loosen it. The combination of Parmigiano Reggiano and Asiago is deliberate: Parmesan provides sharp, salty depth; Asiago is milder and creamier, which softens the sauce's texture and reduces the risk of the cheese seizing into strings rather than melting smoothly.

   

• At 505 calories per 11 oz serving across 2 servings, this is the highest-protein recipe from the September 26 class cluster at 51g per serving — nearly all from the strip steak and shrimp combination. The 7g carbs reflect the absence of any starch component in the serving (the risotto's carbs are accounted for in the full dish build, not this stripped-down nutrition panel). For a special occasion dinner for two, this is as complete a plate as the ATBBQ catalog offers — surf and turf, a composed sauce, a fusion grain dish, and a pickled element all on one plate.
