Ingredients and Preparation

Ingredients

For this recipe, you will need the following ingredients:

• 2 lbs baby potatoes (or larger yellow/red potatoes cut into 1–1.5-inch pieces)
• 1 medium onion, finely diced
• 3 cups mushrooms, sliced
• ¼ cup white wine (Chardonnay)* (optional)
• 1 clove garlic, minced or pressed
• 1 cup heavy whipping cream
• ¼ cup Parmesan cheese, grated (or more to taste)
• 1 teaspoon salt, divided (adjust to taste)
• ½ teaspoon black pepper, divided (adjust to taste)
• ⅓ cup fresh flat-leaf parsley, chopped
• 2 tablespoons olive oil
• ½ cup cooked and sliced chicken or beef (for extra protein, optional)

Ingredient Substitutions and Adjustments

• Potatoes: If you prefer a different texture, try Yukon Gold potatoes for a naturally creamy consistency or Russet potatoes for a fluffier texture.
• Mushrooms: Button mushrooms, cremini mushrooms, or even portobello mushrooms can be used interchangeably.
• White Wine: If you prefer not to cook with wine, replace it with chicken broth or beef broth for added depth of flavor.
• Dairy-Free Option: Use coconut cream or cashew cream instead of heavy whipping cream. Replace Parmesan with a dairy-free alternative or nutritional yeast for a cheesy flavor.
• Meat Addition: Instead of traditional bacon, this recipe works wonderfully with sautéed chicken or beef. Simply cook your protein beforehand and stir it in at the end.

Step-by-Step Instructions

Step 1: Prepare the Potatoes

1. Thoroughly scrub the potatoes under running water to remove any dirt. If using larger potatoes, cut them into 1–1.5-inch pieces to ensure even cooking.
2. Place the potatoes in a large pot and cover them with water. Add 1 teaspoon of salt to the water to season the potatoes as they cook.
3. Bring the water to a boil and let the potatoes cook for about 15-20 minutes, or until they can be easily pierced with a fork. Avoid overcooking, as they should remain firm enough to hold their shape in the sauce.
4. Once cooked, drain the potatoes and set them aside.

Step 2: Cook the Mushrooms and Onions

1. While the potatoes are cooking, clean the mushrooms by gently wiping them with a damp paper towel to remove any dirt. Avoid washing them under running water, as they can absorb excess moisture.
2. Slice the mushrooms into ¼-inch thick pieces.
3. Peel and finely dice the onion.
4. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the diced onions and sauté until they become translucent and slightly golden, about 3-4 minutes. Remove the onions from the skillet and set them aside.
5. Add another 1 tablespoon of olive oil to the same skillet. Increase the heat to high and add the sliced mushrooms. Sauté for about 2-3 minutes, stirring frequently, until the mushrooms are browned and their moisture has evaporated.

Step 3: Deglaze the Pan and Make the Sauce

1. Reduce the heat to medium and pour in the ¼ cup white wine (or substitute with broth). Use a wooden spoon to scrape up any browned bits from the bottom of the pan. This step enhances the flavor of the dish.
2. Allow the liquid to cook off completely, which should take about 1-2 minutes.
3. Lower the heat to medium-low and add the cooked onions, drained potatoes, and minced garlic to the pan. Stir everything together.
4. Pour in the 1 cup heavy whipping cream and stir gently to coat all the ingredients.
5. Season with ½ teaspoon black pepper and adjust the salt as needed.
6. Let the sauce simmer for 2-3 minutes, allowing it to thicken slightly.

Step 4: Add Parmesan and Finish the Dish

1. Once the sauce has thickened, add the ¼ cup grated Parmesan cheese and stir to combine. The cheese will melt into the sauce, adding a creamy, salty richness.
2. If you are including cooked chicken or beef, stir it in at this stage and let it warm through for an additional minute.
3. Remove from heat and stir in the ⅓ cup chopped parsley for freshness.

Step 5: Serve and Enjoy

• Serve the dish immediately while warm. The creamy garlic-Parmesan sauce pairs well with a variety of main courses or can be enjoyed on its own.
• Garnish with extra Parmesan and freshly cracked black pepper for added flavor.

Beginner Tips and Notes

Cooking Tips for Success

• Avoid Overcooking the Potatoes: Keep an eye on them while boiling. Overcooked potatoes can become too soft and fall apart in the sauce.
• Proper Mushroom Sautéing: Cooking mushrooms over high heat prevents them from becoming soggy. They should develop a golden-brown color before adding liquid.
• Balancing the Sauce: If the sauce is too thick, add a small amount of broth or cream to loosen it. If too thin, let it simmer for an extra minute to reduce.

Troubleshooting Common Issues

• Potatoes Too Mushy? Next time, reduce the boiling time and check doneness earlier.
• Sauce Too Salty? Add a splash of unsalted broth or a little more cream to balance it out.
• Mushrooms Releasing Too Much Water? Ensure your pan is hot before adding them and do not overcrowd the skillet.

Serving Suggestions

• As a Side Dish: Serve with grilled chicken, roasted beef, or baked fish for a complete meal.
• As a Main Dish: Enjoy it on its own with a simple green salad.
• With a Sauce: Pair with a drizzle of balsamic reduction or a squeeze of fresh lemon juice for added brightness.

Storage and Reheating Tips

• Refrigeration: Store leftovers in an airtight container for up to 3 days.
• Reheating: Warm on the stovetop over low heat, adding a splash of cream or broth to refresh the sauce.
• Freezing: Not recommended, as the cream-based sauce may separate when thawed.
