Your Simple Ingredient Checklist
- 3 pounds Yukon gold potatoes, partially peeled and washed real good
- 3-4 tablespoons vegan butter for creamy mashiness
- Sea salt and black pepper to taste, cause seasoning’s a must
- 1 tablespoon olive oil to get things sauteing just right
- 1 medium onion, diced up pretty small to melt into the mix
- 2 cloves garlic, minced, for that punch of flavor
- 1 ½ cups uncooked brown or green lentils, rinsed and drained so no grit sneaks in
- 4 cups vegetable stock to soak up all those good tastes and keep lentils tender
- 2 teaspoons fresh thyme, or 1 teaspoon dried if you don’t got fresh on hand
- 1 10-ounce bag frozen mixed veggies with peas, carrots, green beans, and corn for color and crunch
- Optionally, 2 tablespoons tomato paste for depth and a little tang

The Exact Process From Start to Finish
- Preheat your oven to 400 degrees Fahrenheit, that’s about 205 Celsius, for crisping later.
- Place those Yukon gold potatoes in a big pot and cover with water. Bring to a boil till they’re tender, that takes about 15-20 minutes. You know they’re ready when a fork gives a tender pull.
- Drain potatoes and pop them back in the pot. Add vegan butter, salt, and pepper. Mash it all up till it’s smooth and creamy; set aside so the filling can take the stage.
- Heat your olive oil in a large skillet over medium heat. Saute diced onion for about 5 minutes till soft and golden-ish.
- Add your minced garlic and cook for one more minute, smelling that little bounce of aroma.
- Stir in tomato paste, let it cook for 2 more minutes to bring out a deeper flavor.
- Add lentils, veggie stock, sea salt, pepper, thyme, and frozen mixed veggies. Bring to a boiler-up then let it simmer till lentils absorb most liquid and get tender, about 25 minutes. You want it thick but not dry.
- Transfer that lentil veggie goodness to a baking dish. Spread your mashed potatoes evenly on top, smoothing it down for a nice crust later.
- Pop it in the oven and bake for 20 minutes or till the top’s golden and filling bubbles up with joy.
- Let it cool a bit before you dive in; you’ll thank me when your tongue isn’t scorched.

Easy Tweaks That Make Life Simple
- Use pre-made mashed potatoes if you want to skip the boiling and mashing step.
- Swap out frozen mixed veggies for whatever leftover veggies you got in your fridge, like zucchini or mushrooms.
- If you gotta go ultra quick, canned lentils work but add them later to avoid mushiness.
- Try adding some smoked paprika or a dash of soy sauce for a different kinda depth without extra effort.
The Flavor Experience Waiting for You
You sense the earthy vibes from those lentils mingled with savory onions and thyme. It feels like home in a bite.
The mashed potatoes up top got this buttery, fluffy feel that melts in your mouth, carryin’ just enough salt and pepper to make you smile.
The mixed veggies add little pops of sweetness and crunch that keep every bite interesting and fresh.
That slow simmer in the pressure cooker lets all the flavors hug each other tight, so you get this rich, cozy warmth that comforts you after a long day.
How to Store This for Later
Let leftovers cool completely before you stash them away. This keeps that creamy texture nice and stable.
Store in airtight containers for fridge life up to 3-4 days. Just reheat in your microwave or oven till warm and cozy.
Freezing works great too for longer hangs. Portion it out in freezer-safe bags or containers, but remember the mashed potatoes might get a little crumbly when thawed — just mash it a bit before reheating.
Everything Else You Wondered About
- Can I make this gluten-free? Totally! Just check your veggie stock’s gluten-free, and you’re good.
- What if I don’t have fresh thyme? No worries, dried thyme works at half the amount, so 1 teaspoon for 2 teaspoons fresh.
- Can I swap green lentils for red ones? You can, but red lentils cook faster and get mushy, so adjust your simmer time accordingly.
- What’s the best way to know when pressure is ready? Keep an eye on the float valve — once it rises, your cooker is sealed tight and working.
- How do I prevent potatoes from getting watery? Peel partially and mash with vegan butter to keep the texture creamy without being runny.
- Can I prepare this ahead? Yeah, you can cook the lentils and mash separately and assemble before baking for convenience.
