Making stuffing muffins is a straightforward process. Follow these steps to ensure success:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C). Grease a muffin tin or line with muffin liners.
2. Sauté Vegetables: In a skillet, melt the butter over medium heat. Add the diced onion and celery. Sauté until the vegetables are tender, about 5-7 minutes.
3. Prepare Bread: In a large bowl, place the cubed bread. Pour the sautéed vegetables over the bread cubes, mixing well to combine.
4. Mix Broth and Seasonings: In a measuring cup, combine the chicken or vegetable broth with sage, thyme, salt, and black pepper. Mix to combine.
5. Combine Ingredients: Pour the broth mixture over the bread and vegetables. Stir until the bread is evenly coated. Add the eggs and mix until everything is well incorporated.
6. Add Cheese: If using, fold in the shredded cheddar cheese for added flavor and richness.
7. Fill Muffin Tin: Spoon the mixture into the prepared muffin tin, filling each cup about three-quarters full.
8. Bake: Place in the preheated oven and bake for 25-30 minutes, or until the muffins are golden brown and crisp on top.
9. Cool: Once baked, remove the muffin tin from the oven. Let the muffins cool in the pan for about 10 minutes before transferring them to a wire rack.
10. Garnish: If desired, garnish with chopped fresh parsley before serving.
