Cut baguette in half lengthwise. Rub garlic clove over all sides of the bread. Cut bread into half-inch cubes and place on a rimmed baking sheet. Sprinkle smoked paprika over bread (about a teaspoon if using half a baguette), then drizzle with olive oil. Finish with a good shake of salt. Mix everything to ensure the bread is well coated and then place in a 350 degree oven for about 10 minutes. Croutons will be lightly browned and crispy when done.
