Roasting pumpkin creates a warm, inviting dish perfect for cozy autumn evenings. This recipe blends garlic, thyme, and vegetable bouillon to bring out the natural sweetness of pumpkin while layering in comforting savory notes. It is a straightforward way to enjoy seasonal flavors and makes a wonderful side that complements everything from casual family dinners to festive gatherings.
I first made this recipe when I wanted something hearty yet simple for a chilly fall night. The house smelled so cozy afterward that it became an instant favorite, and now I include it in my autumn rotation every year.
Ingredients
- Pumpkin: 4 cups pumpkin peeled seeded and cut into 1inch cubes for even roasting and tenderness
- Olive oil: 2 tablespoons olive oil adds richness and helps the pumpkin caramelize beautifully
- Vegetable bouillon powder: 1 teaspoon vegetable bouillon powder provides a subtle savory depth enhancing the flavor
- Garlic powder: Half a teaspoon garlic powder brings mellow aromatic warmth
- Onion powder: Half a teaspoon onion powder adds subtle sweetness balancing the garlic
- Dried thyme: Quarter teaspoon dried thyme contributes earthiness fitting for fall dishes
- Black pepper: Quarter teaspoon black pepper gives gentle heat to round out the seasoning
- Salt: Half a teaspoon salt optional depending on the saltiness of your bouillon powder
- Pumpkin selection: Choose sugar pumpkins or pie pumpkins when possible because they are sweeter and less watery which helps achieve a better texture and flavor
Instructions
- Preheat and Prepare:
- Set your oven to 400 degrees Fahrenheit or 200 degrees Celsius. Prepare the pumpkin by thoroughly peeling, removing the seeds, and chopping into uniform 1inch cubes. Uniform size ensures all pieces roast evenly without some burning while others remain undercooked.
- Season and Toss:
- Put the pumpkin cubes into a large bowl. Drizzle with olive oil then sprinkle the vegetable bouillon powder, garlic powder, onion powder, dried thyme, black pepper, and salt if needed. Toss gently but thoroughly so every cube is coated evenly. This step is crucial for balanced flavor and perfect caramelization.
- Roast to Perfection:
- Arrange the seasoned pumpkin in a single layer on a baking sheet lined with parchment paper. Avoid overcrowding to prevent steaming. Roast for 25 to 30 minutes, flipping the cubes halfway through. The pumpkin should be tender inside with lightly caramelized golden edges at the end.
- Serve and Enjoy:
- Remove from oven and transfer your roasted pumpkin to a serving dish immediately. For an extra touch, garnish with fresh herbs or toasted seeds to add crunch and freshness. Serve warm and enjoy the comforting aroma and flavor.

My favorite part of this dish is the bouquet of thyme mingling with garlic notes as it roasts. It reminds me of quiet autumn afternoons spent with family, where simple foods like this bring everyone together around the table.
Storage Tips
Keep leftovers refrigerated in an airtight container for up to four days. To reheat, gently warm in an oven or skillet to maintain the caramelized texture rather than microwaving, which may make it mushy. You can also freeze the roasted pumpkin cubes before or after roasting. Just freeze flat on a sheet, then transfer to a sealed bag or container for up to three months.
Ingredient Substitutions
If pumpkin is not available, butternut squash makes an excellent alternative with a similarly sweet flavor and smooth texture when roasted. For the vegetable bouillon powder, nutritional yeast or a splash of vegetable broth concentrate can add that savory boost needed. For something a little different, try drizzling pure maple syrup right before roasting to enhance the caramelization and add a subtle complexity.
Serving Suggestions
Roasted pumpkin pairs beautifully with roasted meats like chicken or pork and brings warmth to a hearty autumn salad. Toasted pepitas, walnuts, or pecans add lovely crunch and nutty contrast. Drizzle a little balsamic glaze or sprinkle feta cheese for a sophisticated finish.

Serve warm and enjoy the comforting aroma of roasted pumpkin. This simple side elevates any autumn meal.
Your Recipe Questions Answered
- → Why is my roasted pumpkin mushy instead of crisp?
Excess moisture and overcrowding lead to mushiness. Ensure pumpkin cubes are dry and spaced apart on the baking sheet for proper caramelization.
- → Can I prep roasted pumpkin ahead of time?
Yes, cube and season pumpkin up to a day ahead and store it airtight in the fridge. Roast fresh for best texture and flavor.
- → Is peeling the pumpkin necessary?
Peeling provides consistent texture and flavor. The skin is edible if scrubbed well, though it changes color and texture slightly.
- → What can I use instead of vegetable bouillon powder?
Try nutritional yeast or vegetable broth concentrate for a similar umami depth and savory flavor enhancement.
- → Can I substitute the pumpkin with another squash?
Butternut squash works well, offering a similar texture and a rich nutty sweetness that complements the spices beautifully.
