Kale Pesto Stuffed Mushrooms: From Prep to Plate

Now, let’s dive into the step-by-step process to create these delightful Kale Pesto Stuffed Mushrooms.
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). A hot oven is crucial for achieving that perfect roasted flavor.
Step 2: Prepare the Mushrooms
Gently clean the cremini mushrooms with a damp paper towel to remove any dirt. Carefully remove the stems and set them aside. You can chop them up and add them to the filling if you like!
Step 3: Make the Filling
In a mixing bowl, combine the kale artichoke walnut pesto, gluten-free oats, chopped thyme, chopped parsley, and walnuts. Season with a pinch of salt and pepper to taste. Mix everything well until the ingredients are evenly incorporated.
Step 4: Fill the Mushrooms
Using a spoon, generously fill each cremini mushroom cap with the pesto mixture. Press down gently to ensure the filling holds together.
Step 5: Arrange and Drizzle
Place the stuffed mushrooms on a baking sheet lined with parchment paper. Drizzle a teaspoon of olive oil over the mushrooms to help them brown and add extra flavor.
Step 6: Bake
Bake in the preheated oven for about 20-25 minutes, or until the mushrooms are tender and the tops are golden brown. Keep an eye on them to avoid overcooking!
Step 7: Serve
Once done, remove the mushrooms from the oven and let them cool for a few minutes. Serve warm as an appetizer, side dish, or even a main course alongside a fresh salad. Enjoy the burst of flavors!
Substitutions by Diet

If you have dietary restrictions or simply want to customize your dish, here are some substitutions you can consider:
- Vegan: Ensure the pesto is vegan-friendly by using a dairy-free cheese alternative or omitting cheese altogether.
- Nut-free: Replace walnuts with sunflower seeds or pumpkin seeds for a similar crunch without the nuts.
- Grain-free: Omit the gluten-free oats and use almond flour or ground flaxseeds instead to help bind the filling.
- Keto: Use a lower-carb pesto and skip the oats to keep the carbs in check.
These adjustments will help you tailor the dish to your specific needs without sacrificing flavor.
