🧾 Ingredients
To make these vegan roast potatoes you only need a couple of simple ingredients.
- Russet potatoes: These spuds are the stars of the show, bringing a fluffy texture and a mild, earthy flavor that's perfect for absorbing other tastes.
- Fresh garlic cloves: Garlic adds a punchy, aromatic kick, enhancing the overall flavor profile with its unmistakable zing.
- Fresh rosemary: This herb infuses the dish with a piney aroma and a slightly lemony, peppery taste, elevating the earthy notes of the other ingredients.
- Broccoli: Not just a green delight, broccoli offers a crunchy texture and is packed with nutrients, adding both health benefits and a vibrant color contrast.
- Marmite spread: This unique ingredient brings a deep, savory umami flavor, enriching the dish with its concentrated, yeast-extract goodness.
- Olive oil: A kitchen essential, olive oil is used for its smooth, fruity notes, and it helps in cooking ingredients evenly while adding a touch of healthy fats.
Substitutions
- Russet potatoes - instead, Maris Piper, King Edward, red potatoes, or Yukon Golds are excellent roast potatoes. You can also use baby potatoes and leave them whole.
- Marmite - use vegemite or nutritional yeast. If you use the latter, add them when adding the broccoli florets.
- Fresh garlic - use garlic powder or all-purpose seasoning instead.
- Olive oil - grapeseed oil and avocado oil are suitable high-smoking point oil substitutes.
- Rosemary – a classic herb for roast potatoes, but thyme would also be a great choice (or both!). Dried basil, oregano, or Italian seasoning also work.
- Broccoli - you can easily change these for cauliflower florets or carrot chunks.
🍽 Equipment
Make sure you use a large baking sheet since the potatoes need "air" to cook evenly; otherwise, the moisture will cause them to become soggy.
🔪 Instructions
Making these roasted potatoes is super easy and requires very little hands-on time.
First, preheat oven to 400 °F (205° C), and prepare potatoes by optionally peeling them and cutting them into evenly sized chunks.
Step 1: Pour the olive oil into a large prepared baking sheet or sheet pan.
Step 2: Put the potato chunks in a large pot of salted boiling water and simmer.
Step 3: Once the oil is hot, remove it from the oven and stir in the marmite.
Step 4: Add the potatoes to the dish and stir well until completely coated.
Step 5: Add the rosemary sprigs and garlic cloves.
Step 6: Remove from heat after 30 minutes.
Step 7: Stir in the broccoli florets and put them back in the oven.
Step 8: Remove from the oven and serve immediately.
💡Expert tip
Slice your potatoes into uniform sizes for consistent cooking and a tender interior.
For those delightful small, round potatoes, keep them whole. But for the larger ones, halve them to guarantee they cook evenly.
📖 Variations
- Zesty - if you like to add a zing, add some lemon juice to the oil and marmite mix, or add lemon zest when adding the broccoli florets.
- Sweet potatoes - this recipe also works with this sweeter option.
- No oil option - if you want to keep this recipe WFPB compliant. Use a parchment-lined baking sheet, and dilute the marmite in 2 tablespoons of warm water. Since the oil makes the potatoes crispy, I recommend you use an air fryer instead of a regular oven to reach the same results.
- Cheesy - add vegan parmesan cheese right before serving. Here's our veggie parm recipe.
- Marmite - if you love truffled dishes, we recently found a Truffle-favored marmite yeast extract, that is so good! Be sure to try it out!

To make this recipe gluten-free, be sure to use a yeast extract brand explicitly marked as so.
🥢 How to serve
Serve these marmite roast potatoes as a side dish with a Holiday Nut Roast, or maple glazed tofu block, and with additional vegetable side dishes like grilled asparagus with toasted almonds, perfectly blanched and buttery white asparagus, and sautéed romanesco broccoli (in case you decide to leave broccoli out of the vegan roast potatoes dish).
❓FAQ
Marmite is a yeast-based spread that's popular in the United Kingdom. It has a robust, salty flavor that some people love and others hate. It's also a good source of B vitamins.
Its taste has been described as being similar to beef bouillon, black licorice, or soy sauce.
Alternative yeast extracts, such as Vegemite or a supermarket brand. Depending on the recipe, you can substitute marmite with nutritional yeast flakes for a cheese flavor or soy sauce or tamari for a more Asian flare.
There is no definitive answer to this question. Some people believe that boiling potatoes before roasting them makes them crispier and drier, while others believe that it makes them moister and less crispy. I prefer to quickly boil the potatoes before roasting them to ensure they are all cooked evenly and you're not left with any hardened ones, but I know many people who swear by the boiled-before-roasted method. Try both methods and see which you prefer.
Russet potatoes, Maris Piper, King Edward, Red potatoes, or Yukon Gold are excellent potatoes for roasting. Baby
When cooking potatoes and broccoli together in the same dish, it is better to cook potatoes halfway first and then stir in the broccoli, as we do in this recipe. This is because broccoli florets are more delicate and require significantly less cooking time.
🥡 Storage
This roasted potatoes and broccoli dish can be stored both in the fridge or freezer.
- Fridge – store in an airtight container for up to 3 days. Reheat and crisp back up in the oven or air fryer.

📋 Recipe
Roasted Garlic and Rosemary Potatoes with Marmite
Equipment
Ingredients
Directions
- Preheat the oven to 400 °F (205° C).
- Pour the olive oil into a large baking sheet and put it in the oven to heat up for about 10 minutes.
- Boil. Meanwhile, put the potato chunks in a large pot of salted boiling water and simmer for 8 minutes until starting to become tender. Drain in a colander and set aside.
- Remove. Once the oil is hot, remove it from the oven.
- Stir in the marmite, don’t worry if you see some bubbles. Be careful, as it might spit.
- Add the potatoes to the dish and stir well until completely coated in the marmite oil.
- Add in the garlic cloves and rosemary sprigs, scattering them evenly, then put back into the oven for 30 minutes, turning the potatoes halfway through. Feel free to sprinkle some garlic powder or onion powder for a more intense and garlicky flavor kick.
- Pop in the broccoli florets and stir, then season with salt and pepper and put back in the oven for 10-15 minutes until the broccoli florets have started to brown but not wilt or burn.
- Take a sample; the potato chunks should be crispy and golden but soft on the inside.
- Adjust with salt and pepper.

Ooh how exciting. Marmite has escaped our British shores. What a fun idea to add it to roast potatoes. I'm so going to try this.
Gus
Oh yes! We love marmite, and it is a great source of Vitamin B12! Marmite adds sooo much flavor to this dish, our meat-eater friends always ask if it has some animal component. It really packs lots of umami.
