Tips for the Perfect Garlic Butter Mushrooms & Spinach

• Do Not Overcrowd the Pan: Mushrooms release moisture. Overcrowding will steam them instead of browning. Cook in batches if necessary.
• Butter vs. Oil: A mix of butter and olive oil prevents the butter from burning while keeping flavor rich.
• Fresh Garlic: Minced fresh garlic is essential. Avoid pre-minced jars—they tend to be bitter when sautéed.
• Leafy Greens: Baby spinach wilts quickly, so add it at the end to retain its bright color and nutrients.
• Make Ahead Tip: You can prep mushrooms and garlic in advance and store them in the fridge for up to 24 hours.

Variations

• Creamy Version: Stir in 2 tablespoons heavy cream at the end for a creamy garlic butter sauce.
• Spicy Twist: Add a pinch of red pepper flakes with garlic for subtle heat.
• Cheesy Delight: Top with grated Parmesan or feta before serving.
• Mushroom Medley: Use a mix of shiitake, oyster, and button mushrooms for extra depth of flavor.

Serving Suggestions

• Serve alongside grilled chicken, salmon, or steak.
• Toss with cooked pasta or quinoa for a vegetarian main course.
• Top a baked potato or risotto for added richness.
• Incorporate into omelets or frittatas for breakfast or brunch.
