Ingredients

  • 4 or 5 large onions, peeled and sliced in rounds
  • 1 stick butter or Parkay
  • salt to taste
  • pepper to taste
  • crushed Ritz crackers

Instructions

  1. Boil onions in a saucepan for a few minutes until transparent; drain well.
  2. Place the drained onions in a glass casserole dish.
  3. Dot the onions with butter.
  4. Season with salt and pepper to taste.
  5. Crush Ritz crackers and sprinkle over the top of the onions.
  6. Sprinkle grated Cheddar cheese over the crackers.
  7. Cover the casserole dish.

Tips & Substitutions

For a richer flavor, consider adding sautéed garlic or herbs like thyme to the onions before baking. If you're short on time, you can use pre-sliced onions or even frozen ones. For a lighter version, substitute half the butter with olive oil or use low-fat margarine. Crushed potato chips could also work as a crunchy topping if you don’t have Ritz crackers.

Serving Suggestions

This casserole makes a great side dish for roasted meats or grilled vegetables. It pairs beautifully with a fresh green salad or a bowl of soup for a comforting meal. You can also serve it alongside Fudgy Zucchini Brownies for a delightful dinner experience with a sweet finish.

Storage & Reheating

Store any leftover Onion Ritzy Casserole in an airtight container in the refrigerator for up to 3 days. To reheat, place in an oven preheated to 350°F until warmed through, about 20-25 minutes. You can also microwave individual portions, but the topping may not stay as crispy.

Frequently Asked Questions

Can I make this casserole in advance?

Yes, you can prepare the Onion Ritzy Casserole a day ahead. Assemble it up to the baking step, cover it with plastic wrap, and refrigerate. When ready to serve, remove from the fridge, let it sit for about 30 minutes to come to room temperature, then bake as directed.

What can I substitute for the Ritz crackers?

If you don’t have Ritz crackers, you can use other types of crushed crackers like Town House or even panko breadcrumbs for a different texture. For a gluten-free option, look for gluten-free crackers or use crushed cornflakes instead.

Can I add other ingredients to the casserole?

Absolutely! Feel free to mix in cooked bacon, chopped green onions, or even sautéed mushrooms for added flavor. You can also experiment with different types of cheese like Monterey Jack or pepper jack for a spicier kick.
