Last Tuesday I opened my pantry and half a bag of red lentils tumbled out, followed by a lonely can of chickpeas that rolled across the floor like it was trying to escape. The scene was almost comical: shelves crammed with half-used bags of grains, stray cans tucked behind boxes, and a collection of pasta shapes so random it could’ve been a modern-art installation. Instead of sighing and ordering take-out (again), I grabbed my Dutch oven and decided enough was enough. Out of that chaos came the most surprisingly delicious, soul-warming soup I’ve made all year—Pantry Clean-Out Pantry Soup With Everything.

Think of this recipe as the culinary equivalent of a spring cleaning: it’s practical, satisfying, and somehow turns clutter into comfort. You don’t need to follow it to the letter—because you literally can’t. Every version will be different depending on what’s lurking on your shelves. Yet the method is foolproof, the flavors are layered and bright, and the end result is so cozy you’ll find yourself “accidentally” stockpiling odds and ends just so you can make it again. Perfect for busy weeknights, post-vacation fridge recovery, or any time you want dinner to cost mere pennies and taste like a million bucks.

Ingredients You'll Need

Below is the “template” lineup I used on my first go, plus the reasoning behind each pick and the best swaps. Use what you have—no need to shop unless you’re truly out.

Legumes (pick one or mix): I scooped up ¾ cup of red lentils because they melt into silky goodness and thicken the broth. Green or brown lentils work, but stay intact for a chunkier texture. Canned chickpeas, black beans, or white beans are excellent if you’d rather skip the simmer time. If you have a half bag of split peas, toss those in; they’ll break down and add body.

Whole Grain (pick one): Pearl barley sings here—nutty, chewy, and ready in 25 minutes. Farro, brown rice, or even a fistful of small pasta shapes like ditalini all do the trick. If your grain is quick-cooking (quinoa, millet), add it later so it doesn’t turn to mush. Instant ramen noodles? Crumble one brick in the final five minutes for a nostalgic twist.

Aromatic Base: Classic mirepoix—onion, carrot, celery—keeps the flavor profile universally lovable. Out of celery? Fennel fronds or a sprinkle of celery seed mimic the bright note. Fresh onion can be swapped with a heaping tablespoon of onion powder in a pinch.

Canned Tomato Variety: A 14-oz can of diced tomatoes is my go-to, but crushed, whole peeled (crush them by hand), or even tomato purée all succeed. Fire-roasted versions add instant smoky depth; Italian-style with basil works if you’re leaning herb-forward.

Flavor Boosters: Tomato paste leftover from chili? Stir in a spoonful for caramelized umami. Worcestershire, soy sauce, or a Parmesan rind simmered with the soup adds that “can’t name it” savoriness. A bay leaf or two is non-negotiable for me; dried thyme or oregano can sub in.

Broth vs. Water: Vegetable broth is great if you have it, but plain water plus a generous pinch of salt and herbs still produces a stellar soup thanks to all the vegetables and legumes. Chicken broth amps up the body if you’re not keeping it vegetarian.

Finishing Touches: A squeeze of lemon wakes everything up; a drizzle of good olive oil makes it restaurant worthy. For creaminess, swirl in a spoon of yogurt or coconut milk. Crunch comes from croutons, toasted nuts, or even crushed tortilla chips—whatever is begging to be used.

How to Make Pantry Clean Out Pantry Soup With Everything

Sear the Tomato Paste

Heat 2 tablespoons olive oil in a heavy Dutch oven over medium. Scrape in 1 heaping tablespoon tomato paste (if using) and cook, stirring, until it turns brick red and sticks slightly to the bottom—about 3 minutes. This quick caramelization concentrates flavor and coats every later ingredient in roasty depth.

Sauté Aromatics

Add diced onion, carrot, and celery (about 1 cup each). Season with ½ teaspoon kosher salt plus a few cracks of pepper. Cook 6-7 minutes, stirring occasionally, until vegetables soften and the onion is translucent but not browned. Adjust heat lower if color starts catching.

Bloom Your Spices

Stir in 2 cloves minced garlic, 1 bay leaf, ½ teaspoon dried thyme, and a pinch of red-pepper flakes (optional but lovely). Cook 60 seconds until fragrant; toasting spices in hot fat disperses essential oils and eliminates any dusty taste.

Deglaze with Tomatoes

Pour in one 14-oz can of diced tomatoes with juices. Scrape the bottom with a wooden spoon to lift any stuck bits (fond equals flavor). Let tomatoes simmer 3 minutes so their acidity mellows and melds with the aromatics.

Add Legumes & Grain

Tip in ¾ cup rinsed red lentils and ½ cup pearl barley (or your chosen grain). Stir to coat in the tomato mixture—this light oil barrier prevents grains from clumping later.

Pour in Liquid

Add 6 cups water or broth along with 1 teaspoon kosher salt. Bring to a boil, then reduce to a gentle simmer. Cover partially; cook 20 minutes, stirring once or twice so nothing sticks.

Load the Veggies

Now add any quick-cooking or canned vegetables: diced zucchini, corn kernels, chopped spinach, canned chickpeas, etc. If using quick-cook grains like quinoa, add now. Simmer another 10-12 minutes until lentils break down and barley is tender yet pleasantly chewy.

Season & Brighten

Fish out bay leaf. Taste and adjust salt/pepper. Stir in juice of ½ lemon plus a handful of chopped parsley. If you like creamy textures, blend a cup of soup and return to pot for luscious body without added dairy.

Expert Tips

Control Thickness

Want it brothy? Add an extra 2 cups liquid at the end. Prefer stew-like? Simmer uncovered for 5 minutes, stirring, until reduced to your liking.

Batch Cooking

Double the recipe and ladle cooled soup into quart freezer bags. Lay flat to freeze; they stack like books and thaw quickly under warm water.

Cool Safely

Divide hot soup into several shallow containers to speed chilling; it should be below 40 °F within 2 hours for food-safety peace of mind.

Brighten Later

Acid dulls during storage. Always freshen leftover soup with a squeeze of citrus or a splash of vinegar before serving.

Reheat Like a Pro

Warm gently with a splash of water or broth; aggressive boiling turns lentils to mush and makes grains balloon.

Layer Salt

Salt at the sauté stage and again after simmering. Gradual layering seasons ingredients evenly without over-salting at the end.

Variations to Try

Moroccan Flair: Swap thyme for 1 tsp each cumin & coriander plus a pinch cinnamon. Stir in chopped dried apricots with the liquid and finish with cilantro & toasted almonds.
Coconut Curry: Replace tomato paste with 1 tbsp red curry paste. Swap lemon juice for lime and finish with ½ cup coconut milk. Top with Thai basil & sriracha.
Smoky Southwest: Add 1 chipotle in adobo, minced, during sauté. Use black beans & corn. Season with smoked paprika. Serve crushed tortilla chips & avocado on top.
Green Minestrone: Skip tomatoes; use 6 cups veggie broth. Add 1 cup pesto at the end plus handfuls of baby spinach & kale. Use small pasta instead of barley.
Slow-Cooker Version: Combine everything except lemon & herbs. Cook on LOW 6-7 hours or HIGH 3-4 hours. Stir in freshness at the end.

Storage Tips

Refrigerate cooled soup in airtight containers up to 5 days. The flavors actually improve after 24 hours as legumes and grains absorb seasoning. For longer storage, freeze in labeled freezer bags or containers up to 3 months. Leave 1 inch headspace; liquids expand when frozen. To serve, thaw overnight in the fridge or microwave on DEFROST, then heat gently on the stovetop with a splash of broth. If soup thickened too much, loosen with hot water and adjust seasonings. Avoid repeated re-heats; portion before initial storage so you only warm what you’ll eat.

Frequently Asked Questions

Absolutely. Use SAUTÉ for steps 1-4, then add remaining ingredients (keep lemon & herbs out). Seal and cook on HIGH pressure for 12 minutes with natural release 10 minutes. Stir in lemon and parsley before serving.

Any acid works: apple-cider vinegar, white vinegar, lime juice, or even a tablespoon of pickle brine. Start with 1 teaspoon, taste, then add more if needed.

Yes. Red lentils release starchy foam. Simply skim with a spoon or ignore—it dissipates after simmering and won’t affect flavor.

Sure! Add 2-3 cups canned beans (drained) during step 7 so they heat through but don’t turn mushy. The broth will be thinner, so consider blending a cup if you want creaminess.

Use quinoa, rice, or GF pasta instead of barley/farro. Double-check your Worcestershire or soy sauce if added; choose certified-GF versions.

Brown ½ pound Italian sausage or diced bacon in step 1 before the tomato paste. Drain excess fat and continue with vegetables. Chicken thighs or shredded rotisserie chicken can also be added in step 7.
