To make this Country Vegetable Soup Recipe gluten-free, replace the egg noodles with certified gluten-free pasta, gluten-free rice, or omit the noodles entirely. Confirm that the vegetable broth, French onion soup mix, diced tomatoes, cooked ham, canned beans, Parmesan cheese, seasonings, and all packaged ingredients are labeled gluten-free, as soup mixes and processed meats may contain hidden wheat or gluten-based additives. Cook gluten-free pasta separately if preferred, then add it to individual bowls before serving to prevent it from becoming too soft. Use clean cookware, utensils, and prep surfaces to avoid cross-contamination.
