What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1The most important step is squeezing the spinach completely dry. Excess water will make the casserole soggy and retain potassium.
- 2Use a salt-free seasoning blend to add flavor without sodium. You can make your own with dried oregano, basil, thyme, and garlic powder.
- 3For a slightly different texture, you can use 1/4 cup of cooked white rice instead of the bread cubes.
