Prepare the Livers: Rinse the chicken livers and pat them dry with a paper towel. Trim any connective tissue.
Cook the Onion and Garlic: Heat 1 tablespoon of butter in a pan over medium heat. Add the chopped onion and cook until soft, about 3 minutes. Pour in garlic and sauté until fragrant. It will take about 30 seconds..
Sauté the Livers: Add the chicken livers to the pan. Cook for about 3 minutes per side until browned on the outside but slightly pink inside.
Add Flavor: Sprinkle in thyme, salt, black pepper, and nutmeg. Pour in the chicken broth and simmer for 1 minute. Remove from heat.
Blend Until Smooth: Transfer everything to a food processor. Add the remaining 2 tablespoons of butter and heavy cream. Blend until smooth and creamy.
Chill and Serve: Spoon the pâté into a dish, smooth the top, and refrigerate for at least 2 hours before serving.
Enjoy: Serve with toasted bread, crackers, or fresh vegetables.
