Blackened Shrimp Stroganoff is the kind of pasta dinner I make when I want something creamy, smoky, and still practical for a weeknight table. The shrimp gets a Cajun-seasoned sear first, so it stays tender while the mushrooms, shallots, roasted red peppers, and capers build a savory sauce around the fettuccini. Instead of a heavy canned base, this version uses chicken broth, sour cream, and a little cornstarch for a glossy stroganoff-style finish that clings to the noodles without feeling too rich. I like this recipe for shrimp pasta nights because it feels a little special, but the ingredient list stays familiar and grocery-store friendly. Serve it right from the skillet while the sauce is warm and silky for a relaxed dinner.

Why You’ll Love This Blackened Shrimp Stroganoff

This pasta gives you smoky shrimp, creamy sauce, and enough bright add-ins to keep every forkful balanced. Here’s why:

• Smoky Shrimp Base: Cajun seasoning gives the shrimp a blackened edge before it ever touches the sauce, so the final dish tastes layered instead of flat.
• Creamy Without Being Heavy: Sour cream and broth make a tangy stroganoff-style sauce that coats the fettuccini while still letting the shrimp and mushrooms stand out.
• Practical Pasta Dinner: The recipe uses one main skillet after the pasta cooks, which keeps the process manageable on a busy evening.
• Bright Savory Add-Ins: Roasted red peppers and capers cut through the creaminess with gentle sweetness and briny little pops.
• Flexible for Serving: It works as a family-style pasta bowl, a date-night dinner, or a smaller meal with leftovers tucked away for lunch.

Ingredients You’ll Need

• Fresh shrimp (1 pound): Use peeled and deveined shrimp so the cooking moves smoothly. Pat them dry well for better blackened edges.
• Olive oil (1 tablespoon): Helps the Cajun seasoning toast onto the shrimp without making the skillet greasy.
• Cajun seasoning (1 tablespoon): Adds smoky heat and saltiness. Taste your seasoning first because blends vary quite a bit.
• Fettuccini pasta (6 ounces): Wide noodles catch the creamy stroganoff sauce nicely, but linguine also works if that is what you have.
• Butter (1 tablespoon): Gives the mushrooms a richer start and helps carry the shallot flavor through the sauce.
• Fresh mushrooms (3 cups): Slice them evenly so they brown instead of steaming. Cremini or white mushrooms both fit here.
• Chopped shallots (1 tablespoon): Adds a mild onion flavor that blends smoothly into the creamy sauce.
• Chicken broth (⅔ cup plus 1 cup): The first amount loosens the skillet, while the second mixes with cornstarch to thicken the sauce.
• Sour cream (½ cup): Gives the stroganoff its tangy creaminess. Stir it in gently off direct high heat.
• Cornstarch (1 tablespoon): Thickens the broth into a glossy sauce that holds onto the pasta.
• Roasted red bell peppers (1 jar, 7 ounces): Drain and chop them so they add sweetness without watering down the sauce.
• Capers (1 tablespoon): Their briny flavor keeps the creamy pasta from tasting too rich.

Before You Start

• Dry the shrimp: Moist shrimp will steam in the skillet, so blot them with paper towels before adding the seasoning.
• Slice evenly: Keep the mushrooms similar in thickness so they brown at the same pace.
• Mix the slurry: Whisk the cornstarch into the full cup of broth before it hits the pan to avoid lumps.
• Save the pasta timing: Start the sauce while the pasta cooks so the noodles can go in warm.

How to Make Blackened Shrimp Stroganoff

• Step 1 – Cook Pasta: Boil the fettuccini until just tender, then drain it and keep a splash of pasta water nearby if the sauce needs loosening.
• Step 2 – Season Shrimp: Pat the shrimp dry, toss with olive oil and Cajun seasoning, and let it sit while the skillet heats.
• Step 3 – Blacken Shrimp: Sear the shrimp in a hot skillet until opaque and lightly charred at the edges, then transfer it to a plate.
• Step 4 – Brown Mushrooms: Melt the butter in the same skillet, add mushrooms, and cook until their moisture releases and the edges turn golden.
• Step 5 – Add Shallots: Stir in the chopped shallots and cook briefly until fragrant, scraping up any seasoned bits from the skillet.
• Step 6 – Build Sauce: Add ⅔ cup chicken broth, then whisk the cornstarch with 1 cup broth and pour it into the skillet.
• Step 7 – Finish Creamy Base: Simmer until slightly thickened, lower the heat, then stir in sour cream, roasted peppers, and capers.
• Step 8 – Combine and Serve: Add the pasta and shrimp back to the skillet, toss gently until coated, and serve while the sauce is silky.

How to Know When Blackened Shrimp Stroganoff Is Done

• Shrimp Texture: The shrimp should be opaque, curled into a loose C shape, and tender when pierced.
• Sauce Thickness: The sauce should coat the back of a spoon and cling lightly to the fettuccini.
• Mushroom Color: The mushrooms should look browned at the edges with no watery pool left in the skillet.
• Serving Temperature: The pasta should be hot throughout, and the shrimp should reach 145°F for safe serving.

Tips to Make It Easier

• Use a Wide Skillet: A larger surface helps the shrimp blacken and the mushrooms brown instead of steaming.
• Work in Batches: I sear shrimp in two batches when the skillet looks crowded so each piece gets better color.
• Watch the Salt: Cajun seasoning and capers can both be salty, so taste the sauce before adding anything extra.
• Keep Heat Gentle: I lower the heat before adding sour cream because a hard boil can make the sauce look grainy.
• Loosen as Needed: If the pasta absorbs too much sauce, add a small splash of pasta water or broth.
• Serve Promptly: Creamy shrimp pasta has the best texture right after tossing, while the noodles are still glossy.

How to Store and Reheat

• Fridge: Store cooled leftovers in an airtight container for up to 3 days.
• Freezer: Freeze only if needed for up to 1 month, knowing the sour cream sauce may separate slightly.
• Reheat: Warm gently in a skillet over low heat with a splash of broth until creamy again.
• Microwave: Heat in short intervals, stirring between each one so the shrimp does not turn rubbery.
• Food Safety: Refrigerate leftovers within 2 hours and reheat to 165°F before serving again.
• Best Texture: Add a spoonful of sour cream after reheating if the sauce needs a fresh creamy finish.

Easy Swaps & Add-Ins

• Pasta Swap: Use linguine, egg noodles, or short pasta if fettuccini is not in your pantry.
• Mushroom Choice: Try cremini mushrooms for a deeper savory flavor or white mushrooms for a milder taste.
• Seafood Option: Add scallops with the shrimp, searing them separately so both stay tender.
• Lighter Sauce: Use light sour cream, but keep the heat gentle so the sauce stays smooth.
• More Vegetables: Stir in baby spinach at the end until just wilted.
• Extra Heat: Add a pinch of crushed red pepper if your Cajun seasoning is mild.

What to Serve With Blackened Shrimp Stroganoff

• Green Salad: A crisp salad with lemony dressing keeps the plate fresh beside the creamy pasta.
• Garlic Bread: Toasted bread is helpful for scooping up the last bit of stroganoff sauce.
• Roasted Asparagus: Its earthy flavor pairs well with mushrooms and smoky shrimp.
• Steamed Broccoli: A simple green vegetable adds balance without competing with the sauce.
• Cucumber Tomato Salad: The cool crunch works nicely against the warm Cajun seasoning.
• Lemon Wedges: A small squeeze at the table brightens the shrimp and capers.
