Cook the ravioli according to the package directions. Drain and divide among bowls.
Meanwhile, cook the bacon in a skillet over medium-high heat until crisp, 6 to 8 minutes; transfer to a paper towel–lined plate. Crumble.
Wipe out the skillet and heat the oil over medium heat. Add the garlic and cook, stirring occasionally, until golden, 1 to 2 minutes. Add the spinach, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Cook, tossing, until just wilted, 1 to 2 minutes.
Stir the bacon and lemon juice into the spinach. Spoon the mixture over the ravioli.
