This Olive Garden chicken scampi copycat recipe lets you bring the restaurant’s creamy, garlicky magic home with just a few clever tricks. The secret lies in the celery butter crust and mushroom-marsala sauce that elevates each bite—just like the version that made this dish a classic.

I've perfected this method over years of testing, ensuring the chicken stays tender while developing that signature crispy crust.

The foundation of great scampi begins with properly seared chicken breasts, cooked just until golden and tender. Deglazing the pan with white wine creates a rich base for the sauce, while sautéing mushrooms and shallots builds depth of flavor.

This isn't just about replicating a dish—it's about mastering the techniques that make it unforgettable, from the perfect sear to the velvety marsala reduction.

By the time you plate this dish, you'll have perfectly cooked chicken with a golden crust, smothered in a rich mushroom-marsala sauce that clings beautifully to each piece.

The aroma alone will have everyone gathering at the table, while the first bite delivers that perfect balance of savory, herby, and slightly sweet flavors. This is comfort food at its finest—elegant enough for company but simple enough for weeknight dinners.

Pair with garlic bread and a Caesar salad for the full Olive Garden experience, or serve it as a standout main course. The beauty of this recipe is its versatility—it works for casual family meals or special occasions, all while delivering restaurant-quality results at home.

Let's get started on creating this classic dish that's been a favorite for years.

Ingredients for olive garden chicken scampi copycat

Celery butter crust and mushroom-marsala sauce—just like Olive Garden’s famous dish.

The celery butter crust is where the magic happens. Fresh celery from the grocery store’s produce section (not the pre-chopped kind) gives the best flavor—just chop it fine. For the butter, Land O’Lakes or Plugrah work perfectly, but any unsalted will do. The chicken pieces should be even-sized so they cook at the same rate. I like to trim any excess fat from the breasts before cutting them—it keeps the crust crispier. Trader Joe’s often has great prices on fresh celery and shallots, so I stock up there. If you can’t find shallots, regular onions work in a pinch, but they’re worth seeking out for that extra depth of flavor.

No marsala wine? Substitute with extra white wine plus a splash of balsamic vinegar—it’ll still taste amazing. The cream cheese is non-negotiable for that signature creamy texture, but if you’re watching fat, Greek yogurt works at half the amount. The mushrooms can be swapped for cremini or button varieties—just slice them evenly. Fresh parsley is ideal for garnish, but dried parsley at one-third the amount will do in a pinch. The white wine should be dry and not too sweet—think Pinot Grigio or Sauvignon Blanc. If you’re using a cheaper wine, let it sit out for 10 minutes to open up the flavors before using.

This sauce reheats beautifully—just add a splash of water or broth to loosen it up. Keeps in the fridge for 3-4 days and freezes for 2 months. I like to make extra sauce and freeze it in ice cube trays for quick portions later. The chicken pieces stay tender for about 2 days in the fridge, but I always eat it fresh because it’s that good. For serving, warm the sauce gently and stir in the lemon juice right before plating—it brightens everything up.

Step-by-step instructions for Olive Garden chicken scampi copycat recipe

Here's how to nail that iconic celery butter crust and rich mushroom sauce at home.

Cut the 1.5 lb boneless, skinless chicken breasts into 6 even pieces. In a small bowl, mix the 0.5 cup cold cubed unsalted butter with the finely chopped 2 whole celery stalks, 1 tsp salt, and 0.5 tsp black pepper until well combined. This is your signature crust mixture.

Heat a large skillet over medium heat and add the butter mixture. Let it melt completely while stirring occasionally for about 2 minutes. The butter should foam and the celery should soften slightly but not brown. This step is crucial—it creates that signature celery butter crust that makes this dish taste just like Olive Garden's.

Carefully add the chicken pieces to the skillet, pressing down gently with a spatula to ensure even contact with the butter. Cook for 3-4 minutes per side until the chicken is golden brown and cooked through to an internal temperature of 165°F. Don't overcrowd the pan or the chicken will steam instead of sear.

Here's the thing—you want that crust to form quickly. If you notice the butter starts to smoke or brown too much, reduce the heat slightly. Once the chicken is golden and cooked through, remove it from the skillet and set it aside on a plate, keeping it warm.

In the same skillet, add the sliced 8 oz mushrooms and cook over medium heat for 4-5 minutes until they release their moisture and begin to brown. Add the minced 3 whole shallots and 6 cloves garlic, cooking for another 2 minutes until fragrant.

Pour in the 0.5 cup white wine and 0.25 cup marsala wine, scraping up any browned bits from the bottom of the pan. Let this mixture simmer for 3-4 minutes until it reduces by about half. This reduction is what concentrates all those wonderful flavors into the sauce.

Reduce the heat to low and stir in the 4 oz softened cream cheese until it melts completely, creating a smooth, creamy base for your sauce. Add the 0.5 cup chicken broth and bring everything to a gentle simmer. Let it cook for 2-3 minutes until the sauce thickens slightly.

Finally, stir in the 1 tbsp freshly squeezed lemon juice and season with 0.5 tsp white pepper. Taste and adjust the seasoning if needed—you might want to add a pinch more salt or a splash more lemon juice to brighten the flavors. Return the chicken to the skillet and let it coat in the sauce for 1-2 minutes.

Transfer the chicken and sauce to serving plates and garnish with the chopped 0.25 cup fresh parsley. Serve immediately over pasta or with crusty bread to soak up that delicious sauce. The key to this dish is timing—don't let it sit too long or the sauce will thicken up.

This copycat recipe delivers all the flavors you love from Olive Garden—creamy, rich, and packed with that distinctive celery butter crust. Enjoy your homemade chicken scampi!

Dietary considerations for this olive garden chicken scampi copycat

Gluten-Free Adaptation

This dish is naturally gluten-free if you use certified gluten-free pasta, like Barilla Gluten-Free Fettuccine or De Cecco Gluten-Free Spaghetti. The celery butter crust and sauce remain unchanged, but always double-check labels on ingredients like chicken broth and cream cheese to ensure they’re gluten-free.

I’ve tested this version with my own gluten-sensitive guests—they never notice the difference! 🌱

Dairy-Free Swaps

For a dairy-free version, replace the butter in the crust with olive oil (use ½ cup) and swap the cream cheese for 4 oz of dairy-free cream cheese like Kite Hill or Violife.

The texture stays creamy, though it’ll be slightly lighter. I’ve found that adding 1 tbsp cornstarch to the sauce helps thicken it properly without dairy. 🧈

Lower-Carb Options

Skip the pasta entirely and serve the chicken scampi over cauliflower rice or zucchini noodles for a lower-carb meal. The sauce clings beautifully to both, and the dish still feels hearty.

I like to roast the cauliflower rice first for extra flavor—toss it with 1 tbsp olive oil, ½ tsp garlic powder, and a pinch of salt before serving. 🥦

Protein Modifications

If you’re avoiding chicken, shrimp or scallops work beautifully in this dish. For shrimp, use 1 lb large shrimp peeled and deveined, and reduce cooking time to 2-3 minutes per side.

Scallops should sear for just 1-2 minutes per side—they cook faster than chicken. The sauce remains the same, but the texture becomes even more luxurious. 🦐

Allergy-Friendly Tips

For nut allergies, ensure all ingredients are nut-free (some cream cheese brands process in nut facilities). If you’re avoiding mushrooms, substitute with bell peppers or asparagus—they add a nice crunch.

I’ve also made this with celery root instead of celery for a slightly sweeter, creamier crust. Always check labels on wine and broth for hidden allergens. 🚫
