How to Make Loaded Sweet Potatoes with Spinach, Mushrooms & Avocado
1. Preheat the Oven
Preheat your oven to 425°F (220°C).
Line a baking sheet with parchment paper.
2. Prepare the Sweet Potatoes
Scrub the sweet potatoes thoroughly.
Pat them dry.
Pierce each potato several times with a fork.
3. Season the Potatoes
Rub the sweet potatoes lightly with olive oil.
Sprinkle with salt and black pepper.
4. Arrange on the Baking Sheet
Place the potatoes directly on the prepared baking sheet.
Leave a little space between them.
5. Roast
Bake for approximately 45–60 minutes, depending on size.
The sweet potatoes are ready when a knife slides easily through the center with very little resistance.
6. Check for Tenderness
If the centers are still firm, return them to the oven for another 5–10 minutes.
7. Prepare the Mushrooms
While the potatoes roast, wipe the mushrooms clean.
Slice them evenly.
8. Heat the Skillet
Place a large skillet over medium-high heat.
Add the olive oil and butter if using.
9. Add the Mushrooms
Arrange the mushrooms in the skillet.
Cook for approximately 5–7 minutes.
Avoid stirring constantly at first so they have time to brown.
10. Let the Moisture Evaporate
Continue cooking until the mushrooms release their moisture and the liquid mostly evaporates.
The mushrooms should become browned rather than watery.
11. Add Garlic
Stir in the minced garlic.
Cook for approximately 30 seconds.
12. Season the Mushrooms
Add:
- Smoked paprika
- Garlic powder
- Onion powder
- Salt
- Black pepper
- Red pepper flakes, if using
Stir well.
13. Add the Spinach
Add the spinach in handfuls.
It may look like a lot initially, but it will wilt quickly.
14. Cook Until Wilted
Cook for approximately 1–2 minutes, tossing frequently.
The spinach should be just wilted and still bright green.
15. Remove from the Heat
Turn off the heat.
Taste and adjust seasoning if necessary.
16. Prepare the Avocado
Cut the avocados into slices or cubes.
17. Add Citrus
Toss gently with lemon or lime juice.
Season lightly with salt and pepper.
18. Make the Optional Drizzle
In a small bowl, combine:
- Greek yogurt or sour cream
- Lemon or lime juice
- Olive oil
- Garlic
- Water
- Salt
- Black pepper
Whisk until smooth.
Add a little more water if needed to create a drizzleable consistency.
19. Rest the Potatoes
Once the sweet potatoes are tender, remove them from the oven.
Let them cool for approximately 5 minutes so they are easier to handle.
20. Slice Open
Cut each sweet potato lengthwise down the center.
Do not cut all the way through the bottom.
21. Fluff the Center
Use a fork to gently fluff the inside of each potato.
22. Season the Inside
Add a small pinch of salt and black pepper.
23. Add the Mushroom Spinach Mixture
Spoon a generous amount of the mushroom and spinach mixture into each sweet potato.
24. Add Avocado
Top with avocado slices or cubes.
25. Add the Drizzle
Spoon or drizzle the creamy lemon-garlic sauce over the top if using.
26. Add Garnishes
Finish with any combination of:
- Parsley
- Cilantro
- Green onions
- Feta
- Pumpkin seeds
- Sesame seeds
- Red pepper flakes
27. Serve
Serve immediately while the sweet potatoes and mushroom-spinach filling are warm and the avocado is fresh.
