Ingredients
Instructions
- Saute onion rings in a saucepan in a little butter until almost transparent, then place in a 2-quart casserole.
- Put mushroom soup, milk, celery seed, and grated Cheddar cheese into the same saucepan and heat, stirring until the cheese melts.
- Pour the mushroom mixture over the onions in the casserole.
- Sprinkle with buttered bread crumbs or Ritz cracker crumbs on top.
- Bake, uncovered, in a 350°F oven for about 30 minutes.
Tips & Substitutions
For a richer flavor, consider adding sautéed bell peppers or mushrooms to the onion mixture. You can substitute the mushroom soup with homemade cream of mushroom if you prefer. For a lighter version, use low-fat cheese and milk. If you're short on time, pre-sliced onion rings can save some prep. Pair this dish with a fresh salad for a balanced meal.
Serving Suggestions
This Texas Onion Casserole pairs beautifully with grilled meats or a hearty vegetable dish. Serve it alongside a fresh green salad or some seasoned oven fried potatoes for a complete meal. For a comforting touch, consider a slice of President Truman's Buttermilk Pie for dessert.
