Tofu Frittata
A sliceable baked round of blended firm tofu folded with sautéed red bell pepper, onion, garlic and wilted spinach, savory with nutritional yeast and baked until set into tender wedges.
Why You'll Love This Recipe
All of the sliceable, custardy comfort of a frittata, and not a single egg anywhere in it. Blended firm tofu bakes into a tender, forkable round that holds a wedge, while red bell pepper, onion, garlic and spinach give it the color and heartiness of a classic vegetable bake. It suits a slow weekend morning, a make-ahead breakfast for the week, or a light supper.
Press the tofu, then blend it completely smooth before it goes in the oven. Pressing drives out the water that would otherwise leave the center wet and loose, and blending breaks the tofu into a uniform batter that firms up evenly in the oven the way beaten eggs would set. Nutritional yeast is doing real flavor work here, lending the deep, cheesy, savory note that keeps a plain tofu base from tasting flat. Cooking the vegetables first, especially wilting the spinach until its liquid cooks off, keeps them from weeping into the batter as it bakes.
It is filling because tofu and nutritional yeast make it high in protein, so a wedge holds you through a morning rather than leaving you hungry an hour later. The spinach and red bell pepper add fiber, color, and a real vegetable presence, while olive oil carries flavor and gives the frittata a satisfying richness. It tastes like something you would happily eat any day, not a stand-in.
Ingredients
- 1 1/4 lb firm tofu
- 1/2 cup nutritional yeast
- 5 cups spinach
- 1 red bell pepper, diced
- 1/2 onion, diced
- 3 cloves garlic
- 2 tbsp olive oil
- 3/4 tsp salt
Instructions
- Preheat and prep: Preheat the oven to 375°F (190°C) and brush a baking dish generously with olive oil. Dice the onion and red bell pepper, mince the garlic, and rinse the spinach. Drain the tofu, wrap it in a clean towel, and press firmly for a few minutes to squeeze out excess water so the frittata sets rather than staying wet.
- Saute the vegetables: Heat the olive oil in a skillet over medium heat. Add the onion and red bell pepper and cook, stirring, until softened and the onion turns translucent, about 5 to 7 minutes. Stir in the garlic and cook until fragrant, about 30 seconds. Add the spinach by the handful and cook just until wilted and any released liquid has cooked off. Remove from the heat.
- Blend the base: Break the pressed tofu into chunks and add it to a blender or food processor with the nutritional yeast, salt, and a splash of water. Blend until completely smooth and thick, like a loose batter, scraping down the sides as needed. Add only enough water to keep the blades moving; the mixture should stay spreadable, not pourable.
- Combine: Scrape the tofu base into a bowl and fold in the sauteed vegetables until evenly distributed. Taste and adjust the salt.
- Bake: Spread the mixture evenly into the oiled baking dish and smooth the top. Bake at 375°F (190°C) for about 30 minutes, until the top is set and dry to a light touch and the edges are lightly golden and pulling from the sides. Let it cool and firm up for at least 10 minutes before slicing into wedges so they hold their shape.
Variations
- Sun-dried tomato and herb: Fold chopped oil-packed sun-dried tomatoes and fresh basil into the base for a brighter, more Mediterranean-leaning flavor.
- Smoky paprika: Blend a spoonful of smoked paprika into the tofu base for a warm, smoky depth that plays well with the sweet red bell pepper.
- Mushroom and thyme: Saute sliced mushrooms with the onion and pepper until their liquid cooks off, and add fresh thyme for an earthier, more savory bake.
- Golden turmeric: Add a pinch of ground turmeric and black pepper to the base for a golden color and a gentle earthy warmth.
- Melty cheese top: Sprinkle a handful of shredded cheese over the surface before baking for a browned, bubbly crust; this adds dairy.
Storage & Leftovers
Store leftover wedges in an airtight container in the refrigerator for up to four days. The frittata actually firms up as it chills, so cold slices hold together cleanly and travel well.
To reheat, warm a wedge in a 350°F (175°C) oven or toaster oven for about 10 minutes until heated through, which keeps the top from turning rubbery. A skillet over medium heat with a little olive oil works too and gives the edges a nice crisp; the microwave is quickest but softens the texture.
To get ahead, you can saute the vegetables and blend the tofu base a day in advance and keep them separately in the refrigerator, then fold together and bake fresh. Or bake the whole frittata, cool it fully, and portion into wedges for grab-and-go breakfasts all week.
Notes & Tips
- Press the tofu well: The single biggest factor in a firm, sliceable result is getting the water out. Wrap the tofu in a towel and set a weight on it while you chop the vegetables; a wetter tofu bakes up loose in the middle.
- Choose firm, not silken: Reach for firm or extra-firm tofu. Softer silken tofu will blend beautifully but never fully sets into wedges that hold their shape.
- Nutritional yeast is the savory key: Do not skip it; it is what gives the frittata its cheesy, savory backbone. If yours tastes flat, a little more nutritional yeast usually fixes it better than more salt.
- Cook the spinach dry: Let the wilted spinach and any pooled liquid cook off completely before folding it in. Extra moisture in the vegetables is the other thing that leaves the center wet.
- Let it rest before slicing: Give the baked frittata at least ten minutes out of the oven. It keeps setting as it cools, and a rested wedge lifts out clean instead of crumbling.
- Serve it warm or cold: It is good hot from the oven, at room temperature on a brunch table, or cold from the fridge with a salad or some sliced avocado alongside.
Nutrition & Mindful Eating
- Blended tofu, softened vegetables and a hot oven are all this asks for. The tofu sets into a sliceable custard, the peppers and onion give it sweetness, and the spinach threads green through every wedge, with protein and fiber built in from the start.
- Nutritional yeast is what makes this taste savory and almost cheesy. It is deactivated yeast in flake form, deeply umami, and most brands are fortified so it carries B vitamins including B12 along with that flavor.
- Tofu blended smooth is what lets this slice neatly. It sets firm in the oven and browns lightly on top, and it brings complete plant protein and calcium to a dish that still eats soft and tender.
- Bell pepper and onion are cooked down before they go in, which sweetens them and keeps water out of the batter. Spinach wilts to almost nothing but leaves its iron, folate and dark green color running through the slices.
- Garlic and olive oil start the pan and set the smell of the whole dish, and a good pinch of salt is what pulls the sweetness out of the peppers and keeps the tofu tasting like something.
- As you eat, take in the browned top and the sweetness the peppers picked up in the oven, and have your slices sitting down with something warm to drink rather than standing at the stove.
Frequently Asked Questions
My frittata came out wet in the middle. What went wrong?
Almost always it is excess moisture. Press the tofu firmly before blending, cook the spinach until its liquid fully evaporates, and add only a splash of water in the blender. If it is still soft, give it a few more minutes in the oven and let it rest before slicing.
Can I use a different green instead of spinach?
Yes. Chopped kale, Swiss chard, or arugula all work; sturdier greens like kale just need an extra minute in the pan to soften before you fold them into the base.
Does it taste like eggs?
Not exactly, but it hits the same note: soft, savory, and custardy in a way that feels like a frittata. The nutritional yeast gives it a cheesy, umami richness that stands on its own rather than imitating eggs.
Can I make it in a muffin tin for individual portions?
Yes. Spoon the mixture into a well-oiled muffin tin and bake at the same temperature, checking around the 20-minute mark, since smaller portions set faster. Let them cool before lifting them out so they hold together.
