A delightful vegetarian spread perfect for any occasion.
Heat the butter in a frying pan over medium heat.
Ensure the butter doesn't burn by keeping the heat moderate.
Add the chopped onion and sliced mushrooms to the pan and sauté until golden brown.
Stir occasionally to prevent sticking and ensure even cooking.
Transfer the sautéed mixture to a food processor.
Allow the mixture to cool slightly before processing to avoid steam buildup.
Add the hard-boiled eggs and walnuts to the processor.
Chop the walnuts beforehand for easier blending.
Season with salt and pepper, then blend until smooth.
Taste and adjust seasoning as needed.
Transfer the mixture to a serving dish and refrigerate for at least 1 hour before serving.
Chilling helps the flavors meld together beautifully.
