French Onion, Rice and Vegetable Casserole

“I needed to keep the pantry rotating, and wanted a new and different side for roast chicken. Tasty, though... my husband and I like to spice things up a bit, others may want to tone down the seasonings by half to start, then work up towards the full amount to suit your palate.”

Ingredients Nutrition

  • 2 (11 ounce) cans French onion soup, condensed
  • 14 cup water
  • 1 cup brown rice
  • 1 (15 ounce) can mixed vegetables, drained
  • 1 (14 1/2 ounce) can green beans, cut, drained
  • 1 (15 ounce) can peas and carrots, drained
  • 2 (4 ounce) cans mixed mushrooms, sliced, drained
  • 1 cup yogurt, Greek style, plain
  • 1 tablespoon black pepper
  • 1 tablespoon thyme
  • 1 34 teaspoons garlic powder
  • 1 teaspoon cayenne pepper
  • 12 lb cheddar cheese, sharp, grated
  • 1 (2 7/8 ounce) can French-fried onions


  1. Combine soup, water and rice in pan, bring to boil, stir once. Cover, reduce heat and simmer 45 minutes. Stir to mix; pull off heat and let set for 15 minutes.
  2. Meanwhile, combine all canned vegetables in a bowl to mix evenly, set aside.
  3. Combine yogurt and spices until well mixed, fold into rice until well distributed.
  4. In a 9 x 13” baking dish layer ½ of the vegetable mixture, then ½ the rice mixture followed by ½ the cheese. Repeat 1st two layers. Evenly intersperse French fried onions for next layer, top with remaining cheese.
  5. If you made this ahead of time and it is just coming out of the refrigerator, place in a cold oven and bake for 45 min at 475 degrees. Otherwise it might be bubbly and done after 30 minutes or so.
  6. I served this as a side for a store bought roast chicken that I reheated at the same time until the bird had an internal temp of 165 degrees.
  7. The next night --
  8. we had French Onion, Rice and Vegetable Casserole – Revisited --
  9. ½ pan Leftover French onion, rice and vegetable casserole.
  10. 1 pkg chicken gravy.
  11. 2 Tbsp Au Jus.
  12. ¼ C Greek yogurt.
  13. ½ Chicken leftovers, diced; after roasting a chicken my household usually has half the
  14. bird eaten, give or take. If you have less than a quarter of your chicken left you
  15. may need to supplement with additional cooked chicken either you prepare or purchase pre-prepared.
  16. 2 Tbsp milk.
  17. 2 tsp pepper.
  18. Put leftover French onion, rice and vegetable casserole into oven and heat to 375 degrees.
  19. Fix chicken gravy as directed on package, add Au Jus and stir until mixed. Next you will incorporate the yogurt, chicken, milk and pepper. Cook/keep warm over a low heat until casserole comes to temperature To serve, place helping of casserole on plate topped with chicken mixture. Enjoy!
