Ingredients
Instructions
- Cut each onion in half from stem to root end, then slice thinly crosswise.
- In a 3-quart casserole, cook onions and butter on High for 15 minutes, stirring twice.
- Add undiluted beef broth and 1 cup of water to the casserole.
- Cook, covered, on High for 10 minutes, stirring once.
Tips & Substitutions
For a richer flavor, consider adding a splash of red wine or balsamic vinegar while cooking the onions. If you're short on time, pre-sliced onions can be used. You can also substitute the Cheddar cheese with Gruyère for a more traditional French onion soup taste. If you prefer a vegetarian option, use vegetable broth instead of beef broth.
Serving Suggestions
Serve the soup hot with the toasted Italian bread placed on top, then sprinkle with grated Parmesan cheese before serving. This dish pairs beautifully with a fresh green salad for a balanced meal. For a heartier option, consider serving it alongside Meat Loaf (Microwave) for a satisfying dinner.
Storage & Reheating
Store any leftover soup in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of water or broth to maintain the soup's consistency. Reheat in the microwave on medium power, stirring occasionally, until heated through. Avoid boiling to preserve the texture.
