  • Crowd-pleasing: Who doesn’t love a rich, savory mushroom sauce? It’s a guaranteed hit with everyone.

Ingredients

Gathering these simple ingredients is half the fun! Here’s what you’ll need to create this magic:

  • 2 tablespoons unsalted butter: For that rich, buttery base that makes everything better.
  • 1 tablespoon cooking oil: Helps the butter not to burn and gets those mushrooms nice and golden. I usually go for olive oil or a neutral vegetable oil.
  • 12 oz mushrooms, sliced: Your star ingredient! Cremini mushrooms are my go-to for their robust flavor, but feel free to use white button or a mix.
  • 1 onion, chopped: Adds a sweet, savory foundation. A yellow or sweet onion works wonderfully here.
  • 1/2 cup heavy cream: This is what makes it wonderfully decadent and creamy.
  • 1/2 cup milk: Helps to temper the richness of the cream and create the perfect sauce consistency. Whole milk is best for a richer result.
  • 1 teaspoon mixed herbs: I love using a store-bought dried herb blend (like Italian seasoning or herbs de Provence), but you can also use dried thyme, rosemary, or parsley.
  • Salt, to taste: Essential for bringing out all those delicious flavors.
  • Pepper, to taste: A little kick to balance the creaminess. Freshly ground black pepper is always the best!

How to Make It

Alright, let’s get cooking! Grab your favorite skillet and let’s do this.

  1. Melt the goodness: In a skillet over medium heat, melt the butter and cooking oil together. You’ll know it’s ready when the butter is foamy and melted.
  2. Sauté the onion: Toss in your chopped onion and cook, stirring occasionally, until it’s nice and soft and translucent. This usually takes about 5 minutes. It’s starting to smell amazing already, right?
  3. Brown those mushrooms: Add your sliced mushrooms to the skillet. Now, resist the urge to stir them too much at first! Let them sit for a minute or two to get a nice golden-brown color. Continue cooking and stirring until they’re tender and have released their moisture, about 8-10 minutes. This browning step is key for developing deep mushroom flavor!
  4. Creamy transformation: Pour in the heavy cream and milk. Stir everything together, making sure to scrape up any browned bits from the bottom of the pan – that’s where the flavor is!
  5. Add the herbs and simmer: Sprinkle in your mixed herbs. Bring the sauce to a gentle simmer, then let it cook for about 5 minutes. You’ll see it start to thicken beautifully into a luscious sauce.
  6. Season to perfection: Finally, season with salt and pepper to your liking. Give it a taste and add more if needed. You’ve done it!

Substitutions & Additions

This recipe is fantastic as is, but it’s also a wonderful canvas for your creativity! Here are a few ideas:

  • Garlic Lover? Add 2-3 cloves of minced garlic in with the onions and cook for about 1 minute until fragrant.
  • For a Richer Flavor: Swap out some of the milk for more heavy cream, or even a dollop of sour cream or crème fraîche at the end.
  • Veggie Boost: Sauté some chopped spinach or kale in the sauce at the very end until wilted.
  • Cheesy Goodness: Stir in a handful of grated Parmesan cheese or shredded Gruyère cheese until melted for an extra decadent sauce.
  • Umami Bomb: A splash of Worcestershire sauce or a tablespoon of soy sauce added with the cream can deepen the savory notes.

Tips for Success

Here are a few little tricks I’ve learned along the way to make your mushroom sauce even more amazing:

  • Don’t overcrowd the pan: When cooking the mushrooms, make sure they have enough space in the skillet. If your pan is too crowded, they’ll steam instead of browning, and you’ll miss out on that lovely depth of flavor. Cook them in batches if necessary!
  • Taste as you go: Seasoning is personal! Always taste your sauce before serving and adjust the salt and pepper.
  • Prep Ahead: You can chop your onions and slice your mushrooms in advance and store them in airtight containers in the refrigerator. This makes assembly even quicker!
  • Thickening woes? If your sauce isn’t as thick as you’d like after simmering, you can create a slurry by mixing 1 teaspoon of cornstarch with 2 teaspoons of cold water, then whisking it into the simmering sauce. Cook for another minute until thickened.

How to Store It

Leftover mushroom sauce is a treasure! Once cooled, transfer it to an airtight container and store it in the refrigerator for up to 3-4 days. It’s also quite delicious reheated gently on the stovetop or in the microwave. You can even freeze it in freezer-safe containers or bags for up to 2-3 months. Just thaw it in the refrigerator overnight before reheating.

FAQs

Q: Can I use dried mushrooms?

A: Absolutely! Rehydrate about 1 ounce of dried mushrooms according to package directions, then drain them (reserve the liquid for another use!) and add them to the skillet when you would add the fresh mushrooms. You might need a little less liquid in the sauce, so adjust as needed.

Q: What can I serve this mushroom sauce with?

A: Oh, the possibilities are endless! It’s divine over pasta (fettuccine, tagliatelle, or even penne), steak, chicken breasts, pork chops, mashed potatoes, or even as a filling for crepes or omelets. It’s also amazing on toast or as a dip!

Q: My sauce is a little thin, what should I do?

A: No worries! This can happen. You can continue to simmer it gently over low heat, stirring occasionally, to let some of the liquid evaporate. Or, for a quicker fix, use the cornstarch slurry method mentioned in the “Tips for Success” section.
