Begin by dicing the onion, bell peppers, and garlic; set them aside in separate bowls.

In your slow cooker, set it to the sauté function and add 2 tablespoons of olive oil over medium heat. Add the diced onion and garlic, cooking for about 5 minutes until the onion becomes translucent.

Place the chicken thighs directly into the slow cooker over the sautéed onions and garlic, sprinkle sweet and smoked paprika, and toss to combine. Let it sit for 3-5 minutes.

Stir in the diced bell peppers and roasted cherry tomatoes, ensuring even distribution. Let them mingle with the chicken and spices for a minute.

In a separate bowl, whisk together the sour cream and heavy cream until smooth. Season with salt and pepper, then pour this creamy mixture over the chicken and vegetables.

Cover the slow cooker and set it to cook on low heat for approximately 6 hours. Ensure the chicken is tender and cooked through.

Once cooked, dish out generous portions and garnish with crispy fried shallots and parsley. This Rustic Hungarian Paprika Chicken pairs well with egg noodles or mashed potatoes.
