high-protein red lentil quinoa spinach & feta loaf (vegetarian & gluten-free)
if you’re looking for a hearty, high-protein vegetarian meal that’s comforting, satisfying, and easy to prep ahead — this red lentil quinoa spinach & feta loaf is it!
it’s made with soaked red lentils and quinoa, blended with eggs, herbs, garlic, and onion, then packed with spinach and salty feta for a flavorful, nourishing sliceable loaf.
taste + texture
this loaf has a savory, slightly earthy flavor with pops of saltiness from the feta and freshness from the spinach.
the red lentils give it a soft but sturdy bite, while the quinoa adds subtle texture throughout.
it bakes up dense and moist but holds together beautifully when sliced — especially after cooling completely.
it’s kind of like a cross between a baked veggie terrine and a protein-packed meatless meatloaf.
why it’s protein-packed
each thick slice has around 15 grams of protein, thanks to the combo of red lentils, quinoa, eggs, flaxseed, and feta.
this makes it an awesome option for vegetarians looking to hit their protein goals!
it’s also rich in fiber, healthy fats, and complex carbs, so it’ll keep you full and fueled.
substitution options
this loaf is super flexible:
- use almond flour instead of oat flour if you want it grain-free but the texture may be a bit more doughy.
- skip the feta for a dairy-free version or try a vegan feta alternative
- swap spinach for finely chopped kale, chard, or grated zucchini (just squeeze it dry!)
- seasonings can be customized — oregano is great, but feel free to try basil, cumin, or a pinch of chili flakes if you want a little heat
how to eat it as a balanced meal
pair a slice or two of this loaf with a big side salad, some roasted veggies, or a dollop of hummus or tzatziki.
you can also serve it with a grain like farro, millet, or brown rice for a more filling meal. it’s great warm or cold, and the flavors deepen after a day in the fridge.
add-in ideas
want to change it up? try mixing in:
- chopped sun-dried tomatoes
- olives
- grated carrot or zucchini
- toasted walnuts or sunflower seeds for crunch
storage
let the loaf cool completely, then store slices in an airtight container in the fridge for up to 5 days.
you can also freeze individual slices between parchment paper — just reheat in a skillet or toaster oven for a quick, protein-rich meal.
this is the kind of recipe you’ll want to keep in your regular meal prep rotation.
it’s nourishing, versatile, and makes your fridge feel like a cozy, ready-to-eat café. let me know if you try it!

Easy Vegetarian Protein Loaf With Red Lentils, Quinoa u0026amp; Spinach
Ingredients
Method
- soak lentils and quinoa place the red lentils and quinoa in a bowl, cover with water, and soak for 4–6 hours (red lentils soften quicker than green or brown). drain and rinse very well.
- preheat the oven to 375ºf. line a loaf pan with parchment paper or grease it well.
- blend the base in a high-speed blender or food processor, add the soaked/drained lentils and quinoa, eggs, onion, garlic, olive oil, flaxseed, oat flour, herbs, salt, pepper, and optional lemon juice. blend until thick and mostly smooth with just a little texture left — kind of like more watery hummus.
- fold in the spinach and feta pour the batter into a mixing bowl and stir in the chopped spinach and crumbled feta.
- fill the pan u0026 bake spread the mixture into the prepared bread loaf pan and press it in firmly. bake for 50-52 minutes, or until golden on top and firm in the center. a toothpick should come out mostly clean. you can bake with shredded cheese for a couple of minutes at the end if wanted.
- cool completely before slicing let cool in the pan for at least 15–20 minutes, then remove and let cool fully on a rack before slicing. it holds together best when fully cooled.
