Preheat your oven to 250 degrees Fahrenheit to ensure it’s ready for baking.
In a small bowl, whisk together the olive oil, ranch seasoning mix, dill weed, garlic powder, and lemon pepper seasoning.
Place the oyster crackers in a large bowl and drizzle the seasoned oil over them, tossing to coat each cracker.
Spread the coated crackers in a single layer on a baking sheet (they should have space for even baking).
