Preheat the oven to 425˚F. Line a rimmed baking sheet with parchment paper or a silicone mat.
Add asparagus to the baking sheet, drizzle with oil and season with salt and pepper. Bake until fork tender, about 9 to 12 minutes (you may need to add up to 5 minutes cook time if you have thicker asparagus).
When cool enough to touch, chop into 1 to 2-inch pieces. Set aside.
In the bowl of a food processor, add ricotta, lemon zest, lemon juice, garlic, oil, herbs, salt, and pepper. Puree until smooth and creamy. Set aside in the refrigerator until ready to use.
Spread each toasted slice of bread with 1 to 2 Tbsp herbed ricotta. Top with 4 to 6 pieces of asparagus. Serve.
