Preheat the oven to 275 degrees F (135 degrees C).

Combine canola oil, ranch dressing mix, dill, lemon pepper, granulated garlic, onion powder, seasoned salt, and white pepper in a large bowl until thoroughly mixed. Gently toss crackers with the seasoned oil to coat. Spread crackers in a single layer on a jelly roll pan.

Bake in the preheated oven until the crackers are very lightly browned at the edges, 15 to 20 minutes, stirring to bake other sides halfway through cooking. Allow to cool completely before storing in airtight canister or resealable plastic bag.
