Recipe Tips
- Be patient when caramelizing the onions – low and slow is key for the best flavor.
- Don’t overcook the chicken to ensure it stays tender in the final dish.

- Grate the Parmesan fresh for the best flavor and melting properties.
- Taste and adjust seasoning before serving, as the saltiness of the cheese can vary.
Serving Suggestions
This Caramelized Onion and Chicken Linguine is a meal in itself, but you can elevate your dining experience with these pairings:
- Serve with a crisp Arugula and Pear Salad for a fresh contrast.
- Pair with a glass of chilled Pinot Grigio or Chardonnay to complement the creamy sauce.

Storage & Reheating
To store: Keep in an airtight container in the refrigerator for up to 3 days.

Reheating: Warm gently in a skillet over medium-low heat, adding a splash of milk or water to loosen the sauce. Stir occasionally until heated through.
Recipe FAQ
Can I make this dish vegetarian?
Yes, omit the chicken and use vegetable broth instead of pasta water for extra flavor. You could also add roasted vegetables for substance.
How can I make the sauce thicker?
Allow the sauce to simmer for a few extra minutes to reduce, or add a bit more grated Parmesan.
Can I use pre-grated Parmesan cheese?
Fresh is best for melting and flavor, but pre-grated will work in a pinch. Avoid the shelf-stable variety if possible.
What type of BBQ sauce works best?
A slightly sweet, tomato-based BBQ sauce works well, but feel free to use your favorite variety.
Can I prepare any parts of this dish in advance?
You can caramelize the onions ahead of time and store them in the refrigerator for 2-3 days. Reheat gently when ready to use.
