Whole 30 Peppercorn Herb Oil
Every ingredient in this infused oil is exactly what it says it is — olive oil, fresh herbs, whole spices, lemon zest, and salt — which makes it a natural fit for anyone eating clean and avoiding additives, emulsifiers, or hidden sugars that sneak into store-bought finishing oils. The technique is simple but the result is genuinely impressive: gently warming the oil coaxes deep, aromatic flavor from the rosemary and thyme without any bitterness, while cracked black pepper and a hit of red pepper flakes add a slow, satisfying heat. A little lemon zest brightens the whole thing and keeps it from feeling heavy. Drizzle it over roasted vegetables, grilled protein, a bowl of cauliflower mash, or anything that needs a flavor lift without a complicated sauce. The optional parsley stir-in at the end adds a fresh, grassy note that makes it feel almost restaurant-worthy. Keep a jar in the fridge and you'll find yourself reaching for it constantly — it's the kind of pantry staple that quietly upgrades everything it touches.

8 servings
- ½ cup extra-virgin olive oil
- 1 tbsp black peppercorns, coarsely cracked
- ½ tsp red pepper flakes
- 3 sprigs fresh thyme
- 2 sprigs fresh rosemary
- 1 tsp lemon zest (from about ½ lemon)
- ¼ tsp fine sea salt
- 2 tbsp fresh flat-leaf parsley, finely chopped (optional)
Instructions
- 1
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.
- 2
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.
