Let’s cook this comforting casserole step-by-step:

1. Cook the Chicken:

• Heat 1 tablespoon of olive oil in a large skillet over medium-high heat.
• Add the diced chicken breast, season with salt and pepper to taste.
• Cook, stirring occasionally, until the chicken is no longer pink and lightly browned, about 5-7 minutes.
• Once cooked, remove the chicken from the skillet using a slotted spoon and set aside on a plate.

2. Sauté Aromatics:

• In the same skillet (add a touch more oil only if necessary), add the finely chopped onion. Cook over medium heat until translucent and softened, about 3-4 minutes.
• Add the minced garlic and sauté for another minute until fragrant.

3. Build the Sauce Base:

• Pour the chicken broth into the skillet. Use a spatula or wooden spoon to scrape up any flavorful browned bits (fond) from the bottom of the pan while the broth simmers briefly.
• Reduce the heat to low. Stir in the heavy cream, the can of cream of chicken soup, and the Ranch seasoning mix. Whisk or stir until the sauce is smooth and well combined.

4. Add Chicken and Gnocchi:

• Gently fold the cooked chicken back into the sauce in the skillet.
• Add the potato gnocchi to the skillet. Stir gently to coat everything in the sauce.
• Simmer for an additional 5-7 minutes, stirring occasionally, until the gnocchi is tender and heated through. (If using dried gnocchi that requires longer boiling, cook it mostly according to package directions separately first, then add here for the last few minutes).

5. Prepare for Baking:

• Preheat your oven to 375°F (190°C).
• Transfer the entire chicken and gnocchi mixture from the skillet to a lightly greased 9×13-inch baking dish. Spread it out evenly.

6. Top and Bake:

• Sprinkle the shredded cheddar cheese evenly over the top of the casserole.
• Add the cooked, crumbled bacon over the cheese layer.
• Bake in the preheated oven for 15-20 minutes, or until the cheese is melted, bubbly, and lightly golden brown.

7. Garnish and Serve:

• Once out of the oven, let the casserole cool slightly for a few minutes.
• Sprinkle with chopped fresh parsley before serving. Serve warm.

A comforting, cheesy bake ready to enjoy!
