Step 1: Grill the Chicken
Preheat a grill pan or outdoor grill to medium-high heat.
Coat the chicken breasts with olive oil, Italian seasoning, garlic powder, salt, and pepper.
Grill for 4-5 minutes per side, or until the internal temperature reaches 165°F (74°C).
Remove from the grill and let it rest for 5 minutes, then slice thinly.
Step 2: Cook the Tortellini
Bring a large pot of salted water to a boil.
Add the tortellini and cook according to the package instructions (usually 3-5 minutes for fresh tortellini).
Drain and set aside.
Step 3: Make the Asiago Alfredo Sauce
In a large skillet over medium heat, melt the butter.
Add the garlic and sauté for 30 seconds until fragrant.
Pour in the heavy cream and milk, stirring constantly.
Gradually whisk in the Asiago and Parmesan cheeses until fully melted.
Season with salt, pepper, and nutmeg (if using).
Simmer for 2-3 minutes, stirring often, until thick and creamy.
Step 4: Assemble the Dish
Add the cooked tortellini into the sauce and gently toss to coat.
Top with sliced grilled chicken.
Garnish with fresh parsley and extra Asiago cheese.
