Ingredients for 17 day diet soup

Six servings of nutrient-dense ingredients designed to optimize protein while minimizing calories.

The lean ground turkey is the protein cornerstone—93% lean or higher ensures maximum muscle support with minimal fat. For the best quality, look for organic or antibiotic-free options at Whole Foods or your local butcher. If turkey isn't available, lean ground chicken works equally well. The fire-roasted diced tomatoes add natural sweetness without added sodium—Muir Glen is a reliable brand for consistent quality. Fresh herbs like thyme and spinach should be bright green and firm, indicating optimal freshness. For the lentils and beans, rinsing thoroughly removes excess starch to prevent gumminess during cooking.

No fresh spinach? Frozen works just as well—thaw and drain before adding. The olive oil should be extra-virgin for its fruity notes that elevate the broth's complexity. If you prefer a smokier profile, swap the cumin for smoked paprika at half the amount. For a vegetarian version, replace the turkey with extra-firm tofu (pressed and crumbled) or tempeh—both provide 10-15g protein per serving. The broth can be substituted with low-sodium vegetable broth, but homemade versions yield the richest flavor. For meal prep, double the batch—this soup reheats beautifully and keeps for 5 days in the fridge or 3 months frozen.

This soup is designed for batch cooking—portion into glass containers for easy reheating. The lentils and beans can be pre-cooked and stored separately for up to 4 days before assembly, saving time. For freezing, wait until fully cooled before transferring to airtight containers. Thaw overnight in the fridge and reheat gently on the stove. The spinach should be added last to preserve its vibrant color and nutrients. For optimal flavor, let the soup sit for 10 minutes after cooking—this allows the spices to meld fully. Each serving delivers 12g protein while keeping calories under 200 per bowl, making it ideal for structured diet plans.

Step-by-step instructions for high-protein diet soup

This method delivers a nutrient-packed, low-calorie soup with 12g protein per serving—perfect for your 17-day weight-loss plan.

Heat the 1 tablespoon extra-virgin olive oil in a large Dutch oven over medium heat. Add the diced yellow onion, 3 whole celery stalks, and 3 medium carrots (peeled and sliced). Sauté for 5-6 minutes until the vegetables soften and the onion becomes translucent.

Here's the thing—don't rush this step. You want the vegetables to release their natural sweetness and develop that caramelized flavor that makes the soup taste homemade. Stir occasionally to prevent browning, but let them cook undisturbed for the last 2 minutes to build depth.

Push the vegetables to one side of the pot and add the 1 lb lean ground turkey to the empty space. Cook over medium-high heat for 5-6 minutes, breaking it apart with a wooden spoon until it's fully browned and cooked through. This ensures maximum protein absorption without excess fat.

When the turkey is nearly done, add the 4 cloves minced garlic, 1 teaspoon dried thyme, 0.5 teaspoon ground cumin, 0.5 teaspoon kosher salt, and 0.25 teaspoon black pepper. Stir everything together for 30 seconds until the garlic becomes fragrant and the spices are evenly distributed. This aromatic base will carry through the entire soup.

Pour in the 6 cups low-sodium chicken broth and add the 1 can (15 oz) diced tomatoes (no salt added), 1 cup green lentils, and 1 cup black beans. Bring the mixture to a gentle boil, then reduce heat to low and let it simmer uncovered for 20-25 minutes, stirring occasionally.

You'll notice the soup thickens slightly as it cooks—that's the lentils and beans releasing their natural starches. This is when the flavors meld together, creating that hearty, satisfying texture. If the soup looks too thick before the 20-minute mark, add ¼ cup water to maintain the right consistency.

Once the lentils and beans are tender (they should be fork-tender but still hold their shape), stir in the 2 cups chopped fresh spinach. Cook for an additional 2-3 minutes until the spinach wilts completely. This final addition boosts the soup's nutrient profile with iron and vitamins while keeping calories in check.

Taste and adjust seasoning if needed—this is where the 0.5 teaspoon kosher salt and 0.25 teaspoon black pepper come into play. Remember, we're using low-sodium ingredients, so don't be afraid to add a pinch more salt if you prefer. The soup should be flavorful but not overly salty.

Remove the soup from heat and let it rest for 5 minutes before serving. This resting period allows the flavors to fully develop and the ingredients to absorb any remaining liquid. I know it's tempting to eat it immediately, but trust me—this short wait makes a noticeable difference in the final taste.

Serve the soup hot, either as a standalone meal or paired with a side of whole-grain bread for added fiber. Each serving delivers 12g of protein, 8g of fiber, and under 250 calories, making it the perfect foundation for your weight-loss journey. The combination of lean turkey, legumes, and vegetables creates a satisfying, balanced dish that keeps you full without the guilt.

Pro cooking tips for this recipe

Broth Selection Matters

Your broth is the flavor foundation—low-sodium chicken broth is ideal, but don't compromise on quality. I swear by homemade broth made from chicken bones simmered with carrots, celery, and onions for depth, or Pacific Foods low-sodium version if you're short on time. Avoid broths with added preservatives or high sodium content, as they'll sabotage your diet goals. 💧

Protein Cooking Technique

Cooking the lean ground turkey separately from the vegetables ensures it browns properly, adding rich flavor without excess fat. Use medium-high heat and break it apart with a wooden spoon—this creates tiny crispy edges that elevate the entire dish. For extra protein, consider adding chickpeas (½ cup) during the simmering phase. They blend seamlessly and add 3g protein per serving.

Vegetable Caramelization Hack

Let your onions, carrots, and celery cook undisturbed for the last 2 minutes—this simple trick develops a natural sweetness through the Maillard reaction. I promise you'll taste the difference. If your vegetables start to stick, add 1 tablespoon water and scrape the bottom with a wooden spoon. This technique works best in a heavy-bottomed pot like a Le Creuset Dutch oven.

Lentil and Bean Timing

Simmer the green lentils and black beans for exactly 20-25 minutes—any longer and they'll turn mushy. If using pre-cooked canned beans, reduce simmering time to 15 minutes. For a fiber boost, add ½ cup diced zucchini during the final 5 minutes of cooking. The lentils should be tender but still hold their shape—this ensures proper texture. 🌾

Spinach Addition Timing

Adding fresh spinach in the last 2-3 minutes preserves its vibrant color and nutrient content. Overcooking wilts the leaves completely, turning them into a mushy texture. For a nutrient powerhouse, stir in 1 tablespoon nutritional yeast along with the spinach—it adds a cheesy flavor and 2g extra protein per serving. This is also when you should taste and adjust seasoning.

Batch Cooking Efficiency

Double the recipe and freeze half for future meals—I portion mine into glass Pyrex containers with snap-on lids for easy reheating. Label with the date and store for up to 3 months. When reheating, add 2 tablespoons water per serving to prevent drying. For meal prep, cook all ingredients except spinach, then refrigerate separately. Add spinach fresh when reheating to maintain crispness. 💡
