Product used:

Parboil Gold




2 cups low-sodium chicken or vegetable broth
10-ounces fresh asparagus, trimmed
4 Tablespoons unsalted butter, divided
3 Tablespoons Riceland Rice Bran Oil or canola oil, divided
1 cup chopped onion
1 cup thinly sliced celery
1 cup chopped bell peppers (use a variety of colors)
1 cloves garlic, minced
1 teaspoon dried thyme leaves, crushed
1 teaspoon dried rosemary leaves, crushed
1 teaspoon Aleppo pepper, optional
8-ounces fresh portobello mushrooms, stemmed and thinly sliced
1 cup heavy cream
Cream of Mushroom Soup Substitute (recipe follows) or 2 (10.5-ounce) cans reduced-sodium cream of mushroom soup
1 cups frozen sweet peas, thawed
2 cups cooked Riceland Gold Perfected Rice
2 teaspoons kosher salt
1 teaspoon freshly cracked black pepper
2 cups freshly shredded cheese, divided use (I used Sharp White Cheddar and Smoked Gruyere. Use a full-flavored cheese of your choice. See Notes.)
1 1/4 cups panko
Fresh flat-leaf parsley as garnish
2 cups cooked, chopped chicken or fully-cooked hickory smoked ham, optional


  1. Prepare Cream of Mushroom Soup Substitute if using.
  2. Preheat oven to 350 degrees F.
  3. In a large skillet, bring broth to a simmer. Add in asparagus and simmer 4-5 minutes until slightly tender.
  4. Remove asparagus to a bowl of ice water to stop the cooking; drain, cut into 2-inch pieces and set aside. Discard broth.
  5. Wipe the skillet dry and return to medium heat; add in 2 Tablespoons unsalted butter and 2 Tablespoons oil and heat until butter is melted.
  6. Add onion, celery and bell peppers to skillet and saute until tender, 3-5 minutes.
  7. Add minced garlic, thyme, rosemary leaves and Aleppo pepper (if using) to skillet; continue to saute 3-4 minutes until garlic is tender. Set aside in a small bowl.
  8. Return skillet to heat, add 1 Tablespoon butter and 1 Tablespoon oil. Add sliced mushrooms to skillet and saute, stirring occasionally, until they are tender and just beginning to color.
  9. Add onion mixture to mushrooms, stirring to combine.
  10. Stir in heavy cream and Cream of Mushroom Soup. Additional cream may be added if mixture appears too thick.
  11. Add peas and rice; mix thoroughly Season with salt and pepper.
  12. Gently stir in 1 1/2 cups shredded cheese.
  13. Spray a 9 x 13-inch casserole with nonstick spray. Layer the bottom with asparagus pieces.
  14. Spread the rice mixture evenly over the asparagus.
  15. Bake at 350 degrees for 25 minutes.
  16. While casserole bakes, prepare toasted panko. Melt 1 Tablespoon butter in a skillet over medium heat. Add in panko and stir frequently until lightly browned; set aside.
  17. After the casserole has baked 25 minutes, top with remaining shredded cheese and bake for 10 minutes before topping with the browned panko. Return to oven for 10 minutes until the panko is toasted well.
  18. Remove from oven and cool 10-15 minutes before serving. Garnish with freshly chopped parsley.

Notes: Avoid using pre-shredded cheese. It contains an additive which does not always encourage smooth melting.

May also be made in smaller casseroles or individual ramekins. Cooking times will need to be shortened slightly.

Variations: Add in chopped cooked chicken or ham when adding the rice. Bake as directed.

Use frozen mixed vegetables in place of the peas for a colorful and pleasing variation.
