  1. Process mushrooms, onion, and garlic in a blender until mixture is pureed. Melt 2 tablespoons butter in a saucepan over medium heat. Cook and stir the mushroom paste in the melted butter until smooth.
  2. Melt 2 more tablespoons butter in a separate saucepan over medium heat; gradually sprinkle flour into the melted butter, stirring continually. Whisk half-and-half into the flour paste; cook and stir until the sauce is thick and smooth, 4 to 5 minutes. Whisk mushroom mixture into sauce and cook until sauce has thickened a bit more, about 10 minutes. Stir cheese into the sauce; cook until the cheese melts, 2 to 3 minutes. Season with salt and black pepper.

The onion I used was a sweet onion. I did toss a touch of crushed red pepper flake into this sauce with the salt/fresh ground pepper. That was the only change I made. I tossed this sauce with hot fettuccini noodles. My family has fallen in love with this sauce--I really should have doubled it because everyone was bummed there were no leftovers. This is one of THE BEST "alfredo" sauces we've had in a LONG time.

Sorry, but this is a no-go. The directions can't be followed since, for starters, in a regular blender, those vegetables aren't going to budge ... I ended up with a stringy, non-alfredo-tasting mushroom paste. :/

I made this recipe for my family and they loved it. My husband can't stop raving about this recipe. I added the half and half to the blender with the mushrooms, onions and garlic to make it easier to puree the veggies. I will be making this recipe often. Thank you.

Tasty base recipe. The garlic was really overpowering! I added more mushrooms to try and mute the garlic. I did also sneak in a couple additional veggies into the blender. The kids ate it and had no idea that they were eating healthy. I'll make it again but with half the garlic.

I have done this many times and it is delicious! With relatively easy steps it was like eating at a restaurant (and I'm not a great cook). Goes well with a dirty martini! ;)

This sauce is amazing! I literally wanted to bathe in it. It was difficult to stop myself from eating it by the spoonful! I wouldn't change a thing.

Easy, excellent dish!! I added extra garlic and sliced about 6 of the mushrooms; added them with the half and half and let sauce simmer until mushrooms were softened. Also used fresh fettuccine. The dish s a keeper!!
