Freeze Friendly Sheet Pan Sweet and Sour Tempeh Ingredients:
- 12 oz. tempeh, sliced into triangles
- 2 cups fresh pineapple, diced
- 1 red bell pepper, diced
- 1 cup sweet white onion, chopped
For Sauce
- ⅔ cup pineapple juice
- ⅓ cup coconut aminos
- ¼ cup ketchup
- 1 teaspoon minced garlic
For Serving
- ½ cup chopped cilantro, for serving
- 4 cups cooked brown rice
How to Make
Step 1: Prep the Marinade Bag
Whisk the sauce ingredients in a small bowl. Add the tempeh, pineapple, onion, and bell pepper to a 1-gallon zip-top freezer bag. Pour in the sauce, press out excess air, and seal.
Step 2: Quick Marinate, Then Freeze
Marinate in the refrigerator for 10 minutes to jump-start the flavor, then transfer the bag to the freezer. Label with the date and contents.
Step 3: Thaw
Move the bag to the refrigerator 24 hours before cooking to thaw safely and evenly.
Step 4: Bake
Preheat oven to 400ºF. Pour the thawed sweet and sour tempeh mixture onto a medium sheet pan and spread into a single layer. Bake 20-25 minutes, stirring once, until the peppers are tender and the edges of the tempeh are lightly caramelized.
Step 5: Portion
Add 1 cup brown rice to each of 4 meal prep containers. Divide the sweet and sour tempeh evenly, top with cilantro, and refrigerate.
How to Store (Fridge + Freezer)
- Fridge: Store portions in airtight containers for up to 4 days.
- Freezer (make-ahead kit): The raw marinated bag can be frozen for up to 3 months.
- Freezer (cooked leftovers): Cool completely, then freeze in airtight containers for up to 2 months.
- Labeling tip: Note "Sweet & Sour Tempeh + Rice," freeze date, and "reheat 2-3 min microwave" on each container so future-you knows exactly what to do.
- Long-tail help: If you're wondering how to store this meal prep or can I freeze this, the answer is yes, both before and after cooking.
How to Reheat (Best Texture)
- Microwave (fastest): Vent the lid. Heat on High 90 seconds-2 minutes per portion, stir, then another 30-60 seconds as needed.
- Oven (best texture): Transfer to an oven-safe dish, cover loosely, and warm at 350ºF for 10-12 minutes. Add a splash of water to keep rice fluffy.
- From frozen: Thaw overnight in the fridge, then reheat as above. Short on time? Microwave at 50% power for 2-3 minutes, stir, then 1-2 minutes on High.
Helpful Tips & Ingredient Swaps
- Tempeh 101: For milder flavor, steam tempeh for 10 minutes before slicing; it opens up the texture and softens any bitterness.
- No coconut aminos? Use low-sodium tamari or soy sauce; add 1-2 teaspoon maple syrup if you want a touch more sweetness.
- Extra veggies: Add snap peas or broccoli florets to the pan in the last 12-15 minutes.
- Crispier edges: Broil the pan for 1-2 minutes at the end-watch closely.
- Make it gluten-free: Coconut aminos are naturally gluten-free; if swapping, choose a certified GF tamari.
- Rice swaps: Serve with quinoa or cauliflower rice if you prefer.
