Preheat oven to 350 degrees.
Heat 1 tbsp. of olive oil in a 6-quart Dutch oven over medium-high heat. Season chicken thighs with salt & lemon pepper. Add to the Dutch oven and brown 4-5 minutes until the chicken has some nice color (doesn't have to be fully cooked). Remove chicken from the pan.

Add arborio rice and stir frequently until the rice just begins to turn translucent, 1-2 minutes.

Stir in chicken broth and add the chicken pieces. Bring the mixture to a simmer, then cover and bake in the oven for 30 minutes.

Stir in milk, parmesan and peas. Place back in the oven uncovered for another 10 minutes until most of the liquid is absorbed.
