Ingredients for Garlic Butter Mushrooms
Main Ingredients
- 450 g (1 lb) mushrooms (button or cremini work best)
- 2 tablespoons olive oil
- 4 tablespoons unsalted butter
- 4–5 cloves garlic, minced
- ½ teaspoon salt (adjust to taste)
- ¼ teaspoon black pepper
Optional Add-Ins
- 1 tablespoon fresh parsley, chopped
- ½ teaspoon fresh thyme or dried thyme
- A squeeze of lemon juice (optional, for brightness)
Ingredient Notes & Substitutions
- Mushrooms: Cremini mushrooms give a deeper, steakhouse-style flavor, but white button mushrooms are perfectly fine. Larger mushrooms can be halved for more texture.
- Butter: Unsalted butter lets you control the seasoning. Plant-based butter works well for dairy-free diets.
- Garlic: Fresh garlic is essential here. Jarred garlic won’t provide the same aroma or flavor.
- Oil + Butter Combo: Olive oil prevents the butter from burning while still allowing rich flavor.
- Herbs: Parsley adds freshness, while thyme adds earthiness. Use one or both depending on preference.
Step-by-Step Instructions
Step 1 – Prepare the Mushrooms
Gently wipe the mushrooms clean with a damp paper towel or soft brush. Avoid soaking them in water, as mushrooms absorb moisture and won’t brown properly.
Trim the stems if needed and leave smaller mushrooms whole. Larger mushrooms can be halved or quartered for even cooking.
Step 2 – Heat the Pan
Place a large skillet over medium-high heat. Add the olive oil and 2 tablespoons of butter. Allow the butter to melt and become slightly foamy.
Make sure the pan is hot before adding the mushrooms—this is key to getting that deep, golden-brown color.
Step 3 – Sauté the Mushrooms
Add the mushrooms to the pan in a single layer. Let them cook undisturbed for 3–4 minutes. This allows proper browning and prevents steaming.
Stir and continue cooking for another 4–5 minutes, until the mushrooms release their moisture and begin to caramelize. Season with salt and black pepper.
Step 4 – Add Garlic and Butter
Reduce the heat slightly and add the remaining 2 tablespoons of butter along with the minced garlic. Stir continuously for about 30–60 seconds, just until the garlic becomes fragrant.
Be careful not to let the garlic burn—it should soften and release aroma, not turn dark.
Step 5 – Finish and Serve
Remove the pan from heat and sprinkle with fresh parsley or thyme if using. Taste and adjust seasoning as needed. A small squeeze of lemon juice can brighten the flavors, but it’s optional.
Serve immediately while hot and glossy.
Pro Tips for Success
- Don’t crowd the pan: If mushrooms are packed too tightly, they will steam instead of brown. Cook in batches if needed.
- High heat matters: Medium-high heat helps evaporate moisture quickly and encourages caramelization.
- Add garlic at the end: Garlic burns easily, so always add it after the mushrooms are mostly cooked.
- Use a wide skillet: More surface area means better browning.
- Let them sit: Resisting the urge to stir constantly makes a big difference in flavor.
Flavor Variations
- Herb Butter Mushrooms: Add rosemary or sage for a deeper, earthy flavor.
- Creamy Garlic Mushrooms: Stir in a splash of cream or dairy-free alternative at the end.
- Spicy Garlic Mushrooms: Add red pepper flakes or a pinch of smoked paprika.
- Balsamic Mushrooms: Finish with a small drizzle of balsamic vinegar for sweetness and depth.
- Asian-Inspired: Add a splash of low-sodium soy sauce and finish with green onions.
Serving Suggestions
These steakhouse-style garlic butter mushrooms pair beautifully with grilled steak, roasted chicken, or pan-seared fish. They’re also excellent over mashed potatoes, rice, or creamy polenta.
For vegetarian meals, serve them over toast, stir them into pasta, or spoon them over quinoa or couscous. They also make a great topping for burgers, omelets, or baked potatoes.
Storage and Reheating Instructions
Refrigerator:
Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheating:
Reheat gently in a skillet over medium heat or in the microwave in short intervals. Add a small knob of butter if they seem dry.
Freezing:
Freezing is not recommended, as mushrooms can become watery and lose texture after thawing.
