This fragrant infused oil is the kind of finishing touch that makes a simple dish taste like it came from a restaurant kitchen. Warm olive oil coaxes the bold heat of cracked black peppercorns and red pepper flakes into something deeply aromatic, while fresh thyme and rosemary add an earthy, almost woodsy backbone. A hit of lemon zest at the end brightens the whole thing and keeps it from feeling heavy. The gentle low-heat method is key — just enough warmth to bloom the flavors without scorching the herbs or turning them bitter. Once strained, the oil is silky and clean, ready to drizzle over roasted vegetables, grilled bread, pasta, or a good piece of fish. For anyone navigating tree nut concerns, this recipe is completely straightforward — every ingredient is a pantry staple with no hidden surprises to worry about. Make a small jar on Sunday and you'll find yourself reaching for it all week.

Crack the black peppercorns coarsely using a mortar and pestle or the flat side of a heavy skillet — you want rough, uneven pieces, not a fine powder.
Combine the olive oil, cracked peppercorns, red pepper flakes, thyme sprigs, and rosemary sprigs in a small saucepan. Warm over low heat until the oil is fragrant and small bubbles form lazily around the herbs, about 3–5 minutes. Do not let the oil simmer vigorously or the herbs will turn bitter.
