Chef’s Notes

• Chicken thighs remain extra juicy after long cooking.
• Fresh garlic provides the best flavor.
• Add zucchini late so it stays tender-crisp.
• A splash of heavy cream at the end creates a creamy garlic butter sauce.
• For thicker sauce, stir in a cornstarch slurry (1 tablespoon cornstarch mixed with 1 tablespoon cold water) during the last 20 minutes.

Tips

• Brown the chicken in a skillet before slow cooking for deeper flavor (optional).
• Use fresh zucchini instead of frozen.
• Don’t overcook the zucchini.
• Add mushrooms with the chicken since they tolerate long cooking well.
• Spoon the garlic butter sauce over the chicken before serving.
• Leftovers often taste even better the next day.

Serving Suggestions

Serve with:

• Steamed rice
• Mashed potatoes
• Buttered noodles
• Cauliflower rice

Storage

Refrigerator

Store in an airtight container for up to 4 days.

Freezer

Freeze without the zucchini for up to 3 months for the best texture. Add fresh zucchini when reheating if possible.

Stir in ¼–½ cup heavy cream and Parmesan cheese during the last 10–15 minutes of cooking.
