🍽️ SERVINGS: 4
⏱️ PREP: 15 minutes
🔥 ESTIMATED TOTAL TIME: 50–65 minutes
🧾 INGREDIENTS
• 42g butter
• 900g onions, thinly sliced
• 2 garlic cloves, chopped
• 1 tsp fresh thyme
• 2 tbsp plain flour
• 480ml beef or chicken stock, divided
• 1 tbsp olive oil
• 450g chicken breasts or thighs
• Salt and black pepper, to taste
• 1 tbsp balsamic vinegar
• 2–3 tbsp teriyaki sauce
• 2 tbsp Dijon mustard
• 110g Gruyère cheese, grated
👩🍳 HOW TO MAKE IT
1️⃣ Cook the onions: Select SEAR/SAUTÉ — MEDIUM. Melt the butter and cook the sliced onions for 10–15 minutes, until softened and golden.
2️⃣ Add the aromatics: Stir in the garlic, thyme and flour. Cook for 1 minute.
3️⃣ Prepare the onion sauce: Add 240ml stock and simmer for 5 minutes. Stir in the balsamic vinegar, 2–3 tbsp teriyaki sauce and Dijon mustard. Transfer the sauce to a heatproof bowl.
4️⃣ Brown the chicken: Select SEAR/SAUTÉ — HIGH. Add olive oil and brown the seasoned chicken for 4–6 minutes per side.
5️⃣ Pressure cook: Pour the remaining 240ml stock into the pot with the chicken. Scrape the bottom, close the pressure lid, set the valve to SEAL and select PRESSURE — HIGH for 5 minutes. Release pressure according to your Ninja Foodi instructions.
6️⃣ Add the onion sauce: Return the prepared onion sauce to the pot and gently combine with the chicken. Warm through if needed.
7️⃣ Melt the cheese: Sprinkle with grated Gruyère and finish using BAKE/ROAST at 180°C for approximately 3–5 minutes, until melted and lightly golden.
✅ Check that the chicken reaches 75°C internally before serving. Cooking time may vary depending on thickness.
✨ SERVING IDEA: Serve with creamy mashed potatoes, rice or crusty bread!
💡 Pro Tips
• Thinly slice the onions to help them become golden within 10–15 minutes.
• Use 2 tbsp teriyaki sauce for a milder flavour or 3 tbsp for a stronger sweet-savoury taste.
• Scrape the bottom of the Ninja Foodi pot before pressure cooking to avoid a burn warning.
• Keep the onion sauce separate while pressure cooking the chicken.
• Check the chicken's internal temperature before adding the final cheese topping.
