- Heat oven to 350F / 177C. Place one oven rack in the upper third of the oven and another in the lower third.
- Heat a large skillet over medium-high heat. Add cooking oil and then onions. Saute until onions are soft, 3 to 4 minutes. Add chicken and saute until chicken is cooked on the outside (don’t worry if it isn’t cooked all the way through), ~3 minutes more.
- Stir in broccoli and garlic and cook until garlic is fragrant, 2 minutes more.
- Remove skillet from the heat and stir in rice, stock, sour cream and first part of cheese. (You can bake the casserole right in the skillet or transfer it to a baking dish if you prefer.) Top with second part of cheese.
- Bake casserole on the lower rack of the oven until the chicken is cooked through and the cheese is melted and bubbly, 30 minutes.
- While casserole bakes, brush a sheet pan with some oil or spray with nonstick cooking spray. Toss mushrooms with olive oil, thyme and some salt. Spread out on sheet pan. Roast on the top rack of the oven, shaking the pan halfway through cooking, until mushrooms are golden brown and tender, 25 minutes.
- When mushrooms are finished roasting, squeeze lemon juice over top.
- Serve casserole (top with some more sour cream or some hot sauce if you’d like) with mushrooms on the side. Enjoy!
