Recipe Ingredients

Here’s everything you’ll need to create this flavorful pasta:

• 2 tablespoons olive oil – For sautéing chicken and aromatics.
• 12 ounces boneless, skinless chicken breasts, cut into bite-sized pieces – Lean protein that pairs perfectly with pasta.
• 2 garlic cloves, thinly sliced – Adds subtle aromatic flavor.
• 2 large onions, halved and thinly sliced – The star ingredient, bringing sweetness and depth.
• 1 tablespoon balsamic vinegar – Enhances caramelization with tangy richness.
• 1 tablespoon barbecue sauce – Adds smoky-sweet complexity to the onions.
• 10 ounces linguine pasta – Holds the creamy sauce beautifully.
• ½ cup heavy cream – Rich base for the sauce.
• Juice of ½ lemon – Brightens and balances the creaminess.
• 3 ounces freshly grated parmesan cheese (plus extra for serving) – Nutty, salty, and melty.
• ¼ cup chopped fresh parsley – Fresh, herby finish.
• Sea salt & freshly ground black pepper – Essential for seasoning at every stage.

Step-by-Step Instructions

1. Cook the Chicken

Heat olive oil in a large skillet over medium heat. Add chicken and garlic, season lightly with salt and pepper, and sauté for 6–7 minutes until cooked through and lightly golden. Transfer chicken and garlic to a plate and set aside.

2. Caramelize the Onions

In the same skillet, add onions with a pinch of salt. Cook over medium heat, stirring occasionally, for 18–20 minutes until softened and starting to turn golden.

Stir in balsamic vinegar and barbecue sauce, then continue cooking another 15 minutes until onions are deeply caramelized.

3. Cook the Pasta

While the onions are working their magic, bring a pot of salted water to a boil. Cook linguine until al dente according to package instructions. Before draining, reserve 1 cup of pasta water—it’s liquid gold for perfect sauce consistency.

4. Make the Sauce

To the caramelized onions, stir in cream, lemon juice, and parmesan. Bring to a gentle simmer. Add about ¼ cup reserved pasta water to loosen the sauce. Stir well.

5. Combine Pasta & Sauce

Toss the drained linguine into the skillet with the onion sauce. Add splashes of reserved pasta water as needed until the sauce evenly coats the pasta.

6. Finish & Serve

Plate the pasta and top with the reserved chicken, fresh parsley, and extra parmesan. Serve warm and enjoy every savory-sweet bite.

Cooking Tips & Techniques

Patience with Onions – Don’t rush caramelization. Low and slow is the secret to depth and sweetness.

Reserve Pasta Water – Starchy pasta water is the key to a silky, clingy sauce.

Grate Cheese Freshly – Pre-shredded cheese won’t melt as smoothly.

Balance Flavors – Taste at the end and adjust with salt, pepper, or extra lemon juice.

Recommended Equipment

Large Skillet – For caramelizing onions and finishing the sauce.

Slotted Spoon – To transfer chicken without excess oil.

Large Pot – For boiling pasta to al dente perfection.

Wooden Spoon or Spatula – Gentle stirring for onions and sauce.

Cheese Grater – For that freshly grated parmesan goodness.
