Ingredients
1.5 lb boneless, skinless chicken breasts (≈ 680 g)
1/2 cup unsalted butter (113 g)
1 cup chicken broth (240 mL)
1 cup heavy cream (240 mL)
1/2 cup grated Parmesan cheese (≈ 50 g)
6 cloves garlic, minced (about 2 tbsp)
1 medium onion, finely chopped (≈ 1 cup / 150 g)
1 red bell pepper, thinly sliced
1 teaspoon Italian seasoning
1/2 teaspoon salt (adjust to taste)
1/4 teaspoon black pepper
1/4 teaspoon crushed red pepper flakes (optional, for heat)
Fresh parsley, chopped (for garnish)
Optional add-ins: 1–2 tbsp lemon juice (brightens flavors), 1/3 cup dry white wine (add with broth), cooked pasta or rice for serving.
Equipment
4–6 quart slow cooker
Large saucepan or skillet (for sautéing sauce base)
Knife, cutting board, measuring cups/spoons
Two forks or meat shredders (for shredding chicken)
Whisk or spoon for stirring
Step-by-step directions
1. Arrange the chicken (2 minutes)
Place the chicken breasts in the bottom of your slow cooker in a single layer.
Optional (recommended): Quick-sear the breasts 1 minute per side in a hot skillet with a little butter or oil for more depth of flavor. This is optional but tasty.
2. Make the scampi sauce (6–8 minutes)
In a large saucepan over medium heat, melt the ½ cup butter.
Add the finely chopped onion and sauté 3–4 minutes until translucent. Add the minced garlic and cook 30–60 seconds until fragrant (don’t brown the garlic).
Stir in the chicken broth, heavy cream and grated Parmesan. Whisk or stir until the cheese melts and the sauce is smooth. Bring to a gentle simmer (do not vigorously boil). Remove from heat.
Tip: If using white wine, add it with the broth and let it reduce for about 1–2 minutes before adding cream.
3. Combine in the slow cooker (2 minutes)
Pour the warm scampi sauce over the chicken, making sure pieces are well coated. Add the thinly sliced red bell pepper on top. Sprinkle Italian seasoning, salt, black pepper and crushed red pepper flakes (if using).
4. Slow cook (4–5 hours on LOW)
Cover and cook on LOW for 4–5 hours, or HIGH for 2–3 hours, until the chicken is fully cooked and tender. The internal temperature of chicken should be 165°F (74°C).
5. Shred and finish (5–10 minutes)
Remove the chicken breasts to a cutting board or shallow bowl and shred with two forks.
Return the shredded chicken to the slow cooker and stir it into the sauce so every bit is coated. If the sauce seems thin, continue on HIGH for 10–15 minutes to reduce slightly, or thicken with a slurry (see Thickening tips).
Taste and adjust seasoning. Stir in 1–2 tablespoons fresh lemon juice if you like a brighter scampi-style finish.
6. Serve
Spoon the chicken and sauce over pasta, rice, polenta, or zucchini noodles. Garnish generously with chopped fresh parsley and an extra dusting of grated Parmesan.
Thickening tips & sauce fixes
To thicken quickly: Mix 1 tbsp cornstarch + 2 tbsp cold water until smooth, whisk into a small amount of hot sauce, then stir back into the slow cooker and cook on HIGH 10–15 minutes.
No cornstarch: Remove chicken, simmer sauce on the stove to reduce and concentrate. Then add shredded chicken back.
If sauce is too thick: Stir in 2–4 tbsp chicken broth or cream to loosen.
Variations & swaps
Low-carb / juicier: Use bone-in chicken thighs — cook on LOW 5–6 hours and shred.
Dairy-free: Swap heavy cream for full-fat coconut milk and Parmesan for nutritional yeast (changes flavor).
Seafood mashup: Add cooked shrimp in the last 15 minutes for a surf-and-turf scampi.
More tang: Add 1 tbsp Dijon mustard or 1–2 tbsp capers before serving.
Veggie boost: Toss in sliced mushrooms, baby spinach, or halved cherry tomatoes in the last hour.
Make-ahead, storage & reheating
Make-ahead: Assemble sauce and chicken in the slow cooker insert, cover and refrigerate up to 24 hours. Cook when ready.
Refrigerate: Keep leftovers in an airtight container 3–4 days.
Freeze: Freeze cooked chicken and sauce up to 2 months; thaw overnight in the fridge before reheating.
Reheat: Gently reheat on the stove over low heat with a splash of broth, or microwave in short bursts, stirring to keep sauce creamy.
Serving suggestions & pairings
Tossed with linguine or fettuccine for classic scampi-style pasta
Over garlic mashed potatoes or creamy polenta for a comforting plate
With crusty bread to mop up sauce
Side salad with lemon vinaigrette or roasted asparagus to cut richness
Wine pairing: crisp Sauvignon Blanc or Pinot Grigio; non-alcoholic: sparkling water with lemon
Troubleshooting
Chicken dry after shredding: Likely overcooked — next time reduce cook time or use thighs. Always check for 165°F (74°C). Return shredded meat to sauce immediately to rehydrate.
Sauce grainy / split: Avoid boiling the cream; keep sauce at gentle simmer when combining. Whisk Parmesan into warm (not boiling) liquid to melt smoothly.
Too spicy: Omit red pepper flakes or balance with a little honey or extra cream.
