Mushroom Sauce in Microwave

This microwave mushroom sauce is the answer when you need a from-scratch cream sauce but the stovetop is occupied with everything else for dinner. Eight ounces of fresh sliced mushrooms cook with butter in a glass measuring cup, then flour goes in to form a quick paste, broth thickens it into a velvety base, and half-and-half finishes the sauce off. Total active time is fifteen minutes including stirring.

The microwave method has one real advantage over a saucepan: you can’t scorch the bottom. Stir every minute as instructed and the sauce stays glossy and lump-free without constant whisking. The 2-quart glass measuring cup matters too — the wide opening lets steam escape and the spout pours straight onto whatever the sauce is dressing.

Use the sauce on broiled chicken breasts, poured over toast points, spooned over a baked potato, or thinned with a splash more broth as a soup base. Beef broth makes a more robust sauce; chicken broth keeps it lighter and lets the mushroom flavor stay center stage.

Kitchen Tips

• Slice the mushrooms thin and even. Chunky pieces stay rubbery in the short cook time.
• Stir the flour into the butter and mushrooms thoroughly before adding broth. Lumps that form here won’t smooth out later.
• Add broth in a steady stream while stirring, not all at once. Cold broth dropped into hot roux makes pockets of raw flour.
• Stop heating the moment it bubbles after adding cream. Boiling cream breaks the sauce.

Variations

• Add a splash of dry sherry or white wine with the broth for a deeper flavor.
• Stir in a teaspoon of Dijon mustard at the end for tang.
• Use a mix of shiitake and cremini mushrooms for a richer, woodsier flavor.
