Dump-and-Go Soup Recipe
And now back to this soup. I love it because it’s a dump-and-go recipe. I put everything in my Instant Pot, set it for 5 minutes, then walk away. Once it’s cooked, add some lemon juice and spinach if you want, then enjoy!
It’s so easy, I even made a YouTube video of it for kids, so they can make dinner all by themselves! I’ve tweaked the recipe a bit since recording that video, but either version is still really good! Train your kids to make this meal for you!
I usually eat it the simple way, but if you want to be impressive, you can make the optional “beefy” tofu crumbles and plant-based parm to go with it.
However you make it, add some red pepper flakes on top and some fresh basil if you have any. Mmm! I serve this with steamed vegetables or a salad on the side and call it a meal! One really yummy meal.
The big, slurpy noodles are so yummy. I try to get organic whole wheat pasta so it doesn’t have folic acid and all those synthetic additivies, but any type will do.
It’s a bit high in sodium, but I’ve found that it just needs that much for optimal flavor. So maybe don’t eat a lot of other really salty foods that day if you’re worried about it.
Love Lasagna?
You’ve got to try my Whole Food Plant Based Lasagna! The “ricotta” is so tasty!!

This is a favorite dump-and-go meal of ours! It's family-friendly, fit for company, and just so yummy! This is a large batch because we love leftovers for it. It's about 8 bowl fulls. You may want to half it if you don't want leftovers.
- 1 onion, minced
- 8 cloves garlic, minced
- 4 TBSP Italian seasoning (or 2 TBSP dried basil and 2 TBSP dried oregano)
- 1/4 tsp red pepper flakes
- 3 tsp salt
- 1 6-oz can tomato paste
- 1 cup red lentils
- 8 cups water (or vegetable broth and reduce salt by half)
- 1 32-oz jar marinara sauce (can also use 2 14-oz cans of tomato sauce or diced tomatoes)
- 10 lasagna noodles (any type), broken up
- 1/2 cup nutritional yeast
- 1 cup full-fat canned coconut milk
- 1 lemon, juiced (about 2 tablespoons lemon juice)
- 1 large handful spinach (optional)
- on top of your bowl if desired: more red pepper flakes, fresh basil, salt and pepper to taste
- 1 16-oz package extra-firm tofu
- 2 TBSP nutritional yeast
- 1 TBSP soy sauce (or tamari, etc)
- 1 tsp smoked paprika
- 3/4 cup almond flour
- 1/4 cup nutritional yeast
- 1 tsp garlic powder
- 1/2 tsp salt
-
Combine all the soup ingredients into the Instant Pot, except the spinach and lemon juice.
-
Set pressure cooker to 5 minutes, then let it sit for 15 more minutes until you flip the valve to release pressure. Remove lid and stir in spinach and lemon juice. Add salt and pepper to taste.
-
The soup thickens significantly as it cools and the noodles absorb more liquid. Stir in the tofu crumbles and sprinkle with plant-based parmesan if desired!
-
Saute the onion and garlic in a splash of water for about 5 minutes. Stir in all remaining ingredients EXCEPT lasagna noodles. Bring to a simmer and cook for 10 minutes.
-
After 10 minutes, stir in lasagna noodles, breaking them into about 4-5 pieces each. Cook for 7-10 minutes (or however long the package says to boil them). Stir frequently so they don't stick together.
-
To make optional "beefy" crumbles, stir nutritional yeast, smoked paprika, and soy sauce together. Then crumble in the tofu in and coat well. Spread onto a baking sheet and bake at 350 for 30-45 minutes, until crispy and golden brown.
-
Or, use an air-fryer at 370 degrees for 15-20 minutes, stirring until evenly cooked and dried out.
-
Stir tofu crumbles into soup at the very end before serving.
-
Over time, the lasagna noodles soak up a lot of liquid. To reheat, add some water and stir. Then microwave a bowl or heat it all on the stove.
If using gluten-free noodles, you may want to cook them separately and stir them in at the end. I haven't tried gluten-free, but I know they have a more delicate texture and may not do well in the Instant Pot or cooked for a long time on the stove.
Nutrition for 1/8 of the recipe, without tofu crubles or plant-based parm.
This soup was a big hit at my house last night and with some guests! Thanks, Faith!
This was superb!! My toddler devoured it, haha it was so cute! Amazing flavor and very hearty. I would definitely bring this to a potluck or family gathering. Thank you so much! I love how easy it is to throw together and love that there’s red lentils in it bc it’s a great source of iron! Thanks Faith!
We took this to a Halloween soup potluck party. Out of all the soups there, this one was gone first and everyone raved about it.
Not sure what went wrong but I could not get it to work in my instant pot. It burned on bottom when I tried to do the pressure cook. Luckily it cooks fast on the stove. We’ll definitely repeat and just use the stovetop method to start off with.
A Halloween soup potluck sounds so fun!! Now I want to host one, haha. I’m sorry it kept burning in the instant pot.. That’s never happened to me!
