There’s something irresistibly cozy about a plate of creamy fettuccine smothered in rich sauce and tender slices of chicken. This Olive Garden Chicken Alfredo Copycat Recipe captures that restaurant comfort with simple pantry-friendly ingredients and an easy set of steps you can follow on a weeknight or when guests arrive. The final dish is velvety, well-seasoned, and topped with bright fresh parsley for contrast — everything a classic Alfredo should be.

Why this version works

This recipe leans on a few key techniques that produce a luxurious sauce without fuss: browning the chicken to build flavor, adding a little flour as a thickening agent, and gently simmering heavy cream so the sauce becomes silky without breaking. Using freshly grated cheese makes the sauce smoother and avoids gritty textures that pre-grated cheeses sometimes give. The balance of garlic, salt, and freshly ground pepper keeps the profile simple and elegant — the way Olive Garden’s Alfredo feels, but made from scratch at home.

Ingredients

12 ounce fettuccine pasta, dry
2 tablespoons olive oil
3/4 cup unsalted butter
2 chicken breasts, boneless and skinless
1 1/2 teaspoons salt, divided
1 1/2 teaspoons fresh ground pepper, divided
4 cloves garlic, very finely chopped
2 tablespoons all-purpose flour
2 1/3 cups heavy cream
1 cup grated Parmesan cheese (add extra for topping if desired)
1 tablespoon chopped fresh parsley, for garnish

Equipment

Large pot for boiling pasta
Large skillet or sauté pan (at least 10–12 inches)
Tongs or pasta fork
Sharp knife and cutting board
Measuring cups and spoons

Taste and texture tips

If you prefer a thicker sauce, let it simmer a couple of minutes longer before adding the cheese. For an extra-cheesy finish, reserve a little of the grated Parmesan to sprinkle over each plate. Make sure the cream is not boiling aggressively when you add the cheese — a gentle simmer prevents the sauce from separating. Freshly ground pepper gives a brighter, more complex bite than pre-ground pepper, so grind it just before cooking if you can.

Step-by-step directions

Prep: Bring a large pot of salted water to a rolling boil for the fettuccine. Pat the chicken breasts dry with paper towels and season both sides with 1 teaspoon of the salt and 1 teaspoon of the fresh ground pepper. Mince the garlic very finely and grate the Parmesan if not pre-grated. Chop the parsley and set it aside for garnish.

Cook the pasta: Add the 12 ounce fettuccine to the boiling water and cook according to package directions until al dente. Reserve about 1 cup of pasta cooking water, then drain the pasta and set aside.
Brown the chicken: While the pasta cooks, heat 2 tablespoons of olive oil in a large skillet over medium-high heat. When the oil shimmers, add the seasoned chicken breasts. Cook undisturbed for 4–5 minutes until the underside is golden brown. Flip and cook the other side for 4–5 minutes, or until an instant-read thermometer inserted into the thickest part reads 165°F (74°C). Transfer the chicken to a cutting board and let rest for 5 minutes, then slice into strips or bite-sized pieces.
Start the sauce base: Reduce the skillet heat to medium. Add 3/4 cup unsalted butter to the same skillet. Once melted, add the 4 cloves of very finely chopped garlic and sauté for about 30–45 seconds until fragrant, stirring constantly to prevent burning.
Thicken slightly with flour: Sprinkle 2 tablespoons of all-purpose flour into the melted butter and garlic, stirring continuously to create a smooth paste. Cook this mixture for about 1 minute to remove the raw flour taste, continuing to stir so it doesn’t brown.
Add the cream: Slowly pour in 2 1/3 cups heavy cream while whisking or stirring to combine with the butter-flour mixture. Bring the mixture to a gentle simmer over medium-low heat. Allow it to simmer for 2–3 minutes, stirring occasionally, until it begins to thicken slightly.
Season and finish the sauce: Add the remaining 1/2 teaspoon salt and 1/2 teaspoon fresh ground pepper to the sauce. Gradually stir in 1 cup grated Parmesan cheese, a little at a time, until fully melted and the sauce is smooth. If the sauce becomes too thick, stir in a few tablespoons of the reserved pasta cooking water until you reach the desired consistency.
Combine pasta, chicken, and sauce: Add the drained fettuccine directly to the skillet with the Alfredo sauce. Gently toss with tongs or a pasta fork so each strand is evenly coated. Add the sliced chicken and continue to toss until everything is heated through. If needed, add more reserved pasta water to loosen the sauce so it clings smoothly to the pasta.
Serve: Divide the Alfredo between plates or bowls. Sprinkle extra grated Parmesan over each serving if you like, and finish with the 1 tablespoon chopped fresh parsley for color and freshness. Serve immediately while warm.

Make-ahead and storage

You can make the sauce up to one day in advance and refrigerate in an airtight container. Reheat gently on the stove over low heat, stirring in a splash of cream or reserved pasta water to restore the sauce’s silky texture. Cooked pasta is best when combined with the sauce just before serving; if you must store leftovers, keep pasta and sauce separate and combine when reheating.

Variations and substitutions

Vegetable boost: Add steamed or roasted broccoli florets, peas, or sautéed mushrooms when you toss the pasta and chicken into the sauce.
Herb swap: Add a pinch of dried Italian seasoning or a few leaves of torn fresh basil for a herby lift.
Cheese swap: If you prefer a sharper cheese, swap half the Parmesan for Pecorino Romano, keeping the total amount at 1 cup.

Serving suggestions

This Olive Garden Chicken Alfredo Copycat Recipe pairs beautifully with a crisp green salad and a lemony vinaigrette to cut through the richness. Crusty bread or garlic bread make it a full, satisfying meal. For a lighter finish, serve with a simple side of steamed green beans or a tomato-cucumber salad.

Recipe notes

If your sauce separates or looks greasy, remove it from the heat and whisk in a little warm cream or reserved pasta water to bring it back together.
Cook the chicken to a safe internal temperature, then let it rest before slicing to keep the meat juicy.
Freshly grated Parmesan melts more smoothly than pre-grated varieties, so take a minute to grate the cheese if you can.

Final thoughts

This Olive Garden Chicken Alfredo Copycat Recipe is a comforting and elegant dish that’s surprisingly simple to pull together. It’s rich without being heavy when prepared carefully, and the homemade sauce really makes the difference. With just a few basic techniques — browning the chicken, building the sauce slowly, and using good cheese — you’ll have a restaurant-style pasta that feels like a special treat any night of the week.

Ingredients

12 ounce fettuccine pasta (dry)
2 tablespoons olive oil
3/4 cup unsalted butter
2 chicken breasts, boneless and skinless
1 1/2 teaspoons salt, divided
1 1/2 teaspoons freshly ground pepper, divided
4 cloves garlic, very finely chopped
2 tablespoons all-purpose flour
2 1/3 cups heavy cream
1 cup grated Parmesan cheese plus extra for topping if desired
1 tablespoon chopped fresh parsley for garnish

Equipment

Large Pot
Colander
Large Skillet
Tongs or spatula
Knife and cutting board
Measuring cups and spoons

Method

Bring a large pot of salted water to a boil and cook the fettuccine according to package directions until al dente; drain in a colander and toss with a little olive oil to prevent sticking if desired.
While the pasta cooks, heat 2 tablespoons olive oil and 1/4 cup of the butter in a large skillet over high heat.
Season the chicken breasts with 1 teaspoon of the salt and 3/4 teaspoon of the pepper (reserve the remainder). Add the chicken to the hot skillet and cook until golden on both sides.
Cover the pan, reduce heat to medium, and cook the chicken about 5 minutes more or until no longer pink in the center; transfer to a plate, tent with foil, and let rest.
Wipe the skillet if needed, then melt the remaining 1/2 cup butter over medium heat. Add the finely chopped garlic and cook, stirring, about 30 seconds until fragrant.
Reduce heat to low, add the flour and stir to form a paste, then very slowly pour in the heavy cream while stirring constantly until the sauce is smooth.
Cook the sauce over low to medium-low heat, stirring, until steaming and thickened. Stir in 1 cup grated Parmesan until melted. Season to taste with the remaining salt and pepper.
Slice the rested chicken into strips. Divide the drained pasta among plates or bowls, top with chicken, and spoon the Alfredo sauce over everything.
Garnish with chopped fresh parsley and additional Parmesan if desired, then serve immediately.
