Ingredients
- Pumpkin: Four cups of pumpkin, peeled and cut into uniform cubes for even roasting sugar pumpkins are best for their sweetness and firm texture
- Olive oil: Two tablespoons of olive oil from a good quality coldpressed source to add richness and aid caramelization
- Vegetable bouillon powder: One teaspoon of vegetable bouillon powder to bring umami depth check salt levels to avoid overseasoning
- Garlic and onion powder: Half a teaspoon each of garlic and onion powder to subtly enhance flavor without needing fresh aromatics
- Dried thyme: A quarter teaspoon of dried thyme for a gentle herbaceous note ideally Provence thyme for authenticity
- Black pepper: A quarter teaspoon of freshly ground black pepper to balance the sweetness
- Salt: Half a teaspoon of salt optional and adjusted based on the bouillon’s saltiness
Instructions
- Preheat and Prepare:
- Preheat your oven to 200 degrees Celsius for an optimal roasting temperature. Prepare the pumpkin by peeling thoroughly, removing seeds, and cutting into consistent oneinch cubes to allow for even cooking and caramelization. Uniformity here is essential to avoid some pieces being undercooked while others burn.
- Season and Toss:
- Place pumpkin cubes in a large bowl. Drizzle the olive oil evenly over them. Sprinkle the vegetable bouillon powder, garlic powder, onion powder, dried thyme, ground black pepper, and salt carefully. Toss everything gently so each piece is coated in flavor but not drenched in oil. Taking time to coat well ensures balanced seasoning with every bite.
- Roast to Perfection:
- Lay the seasoned pumpkin cubes on a baking sheet lined with parchment paper, making sure they form a single even layer. Avoid overcrowding, as crowding leads to steaming instead of roasting. Roast for about 25 to 30 minutes, turning the pumpkin pieces halfway through. Look for tender flesh with golden brown edges and slight caramelization that signals perfect roasting.
- Serve and Enjoy:
- Remove the pumpkin from the oven and transfer it immediately to a serving dish to keep it warm and crispy. Garnish with fresh herbs like parsley or thyme if you desire, or add a sprinkle of toasted seeds for texture. Serve as a side to poultry, pork, or as part of a vegetarian spread for a delightfully hearty and healthy addition.

My favorite ingredient is the vegetable bouillon powder because it adds a deep savory note that lifts the natural sweetness of the pumpkin without overshadowing it. I remember my grandmother preparing pumpkin this way during chilly family gatherings, filling the house with an inviting aroma that still reminds me of those special moments.
Storage Tips
Store roasted pumpkin in an airtight container once cooled and keep in the refrigerator for up to three days. Reheat gently in the oven or on the stovetop to maintain crispiness. For longer storage, frozen cubes can be roasted ahead and defrosted when needed.
Ingredient Substitutions
If pumpkin is not available, butternut squash makes an excellent substitute with a similar texture and sweet profile. Instead of vegetable bouillon powder, nutritional yeast or vegetable broth concentrate offers a pleasant umami flavor. A drizzle of maple syrup just before roasting gives a luscious caramelized glaze, perfect for a twist.
Serving Suggestions
Serve alongside a roast chicken or grilled pork tenderloin to create a comforting autumn meal. Add toasted nuts or seeds on top to introduce crunch and nutty flavors. Mixed into a warm salad with arugula and vinaigrette, roasted pumpkin shines as the star ingredient.

This roasted pumpkin makes a versatile healthy side that pairs well with poultry pork or vegetarian mains. Try adding toasted seeds or a drizzle of maple syrup for extra texture and sweetness.
Common Recipe Questions
- → Pourquoi mon potiron rôti est-il mou au lieu d'être croustillant ?
Un excès d'humidité et un espace insuffisant entre les morceaux empêchent la caramélisation. Séchez bien les cubes et espacez-les sur la plaque pour un brunissage optimal.
- → Peut-on préparer le potiron rôti à l'avance ?
Oui, vous pouvez couper et assaisonner le potiron la veille, le conserver au frais dans un récipient hermétique, puis rôtir à la dernière minute.
- → Faut-il éplucher le potiron avant la cuisson ?
L'épluchage garantit une texture douce et homogène, mais la peau est comestible si bien nettoyée, apportant plus de mâche et une couleur différente.
- → Quel type de potiron est recommandé ?
Les potirons sucrés ou à tarte conviennent parfaitement pour leur goût riche et leur faible teneur en eau, favorisant une bonne cuisson.
- → Peut-on remplacer le bouillon végétal ?
Oui, la levure nutritionnelle ou un concentré de bouillon apportent une profondeur umami intéressante en alternative.
