Preheat the oven to 200°C/400°F. First brown the butter by melting in a small pan, constantly whisking over a medium heat until it becomes foamy, brown and nutty. Pour into a small bowl to stop the cooking and cool completely.
3 tablespoons salted butter
Add the ricotta, cold brown butter, lemon juice and black pepper to a food processor and whip until completely smooth. Taste for seasoning and adjust if desired. Scrape into a bowl and place in the fridge.
1 cup ricotta, 1 tablespoon fresh lemon juice, ⅛ teaspoon freshly ground black pepper
Slice the baguette into ½ inch thick slices on a diagonal. Brush both sides of the slices of baguette with olive oil and place on a baking sheet lined with parchment paper. Bake for 8 to 10 minutes in the oven, until golden brown. Allow to cool. You can also toast the walnuts on the same sheet for 5 minutes.
1 french baguette, 1-2 tablespoons olive oil
