For the Honey Roasted Acorn Squash

Pro Tips

Substitutions and Variations

- Add a pinch of garlic powder to the balsamic sauce.
Make Ahead Tips

- Measure all ingredients and store separately until ready to cook.
- Cook the brown rice ahead and reheat before serving.
Why This Recipe Works
The balsamic vinegar contains natural acids that help flavor the fish while keeping it tender. Brown sugar balances the vinegar’s tangy flavor and helps create a lightly glazed sauce. Cooking the fish in a sealed foil packet traps moisture, which keeps the tilapia from drying out. Slow, gentle heat allows the fish to cook evenly and stay flaky.
Sweet Balsamic Tilapia Recipe
Step 1: Make the Sweet Balsamic Sauce
In a small bowl, whisk together:
- ¼ cup balsamic vinegar
- 2 tablespoons brown sugar
- ¼ teaspoon salt
- ¼ teaspoon black pepper
Mix until the brown sugar is mostly dissolved.
Step 2: Prepare the Fish Packets
Place 4 thawed tilapia fillets on a large sheet of aluminum foil. Pour the sweet balsamic sauce evenly over the fish. Fold and seal the foil tightly to create packets.
Step 3: Slow Cook the Tilapia
Place the sealed foil packets into a black oval crockpot. Cover and cook on LOW for 2 to 4 hours until the fish is white and flakes easily with a fork.
Step 4: Cook the Brown Rice
While the fish cooks, combine 1 cup brown rice and 2 cups water in a saucepan. Cook according to package directions until tender.
Step 5: Prepare the Acorn Squash
Toss 1 sliced acorn squash with 1 tablespoon honey, 1 tablespoon olive oil, ¼ teaspoon salt, and ⅛ teaspoon black pepper until evenly coated.
Step 6: Roast the Acorn Squash
Spread the coated squash slices onto a baking sheet and roast at 400°F for 25 to 30 minutes until tender and lightly caramelized.
Step 7: Serve
Carefully open the foil packets. Serve the sweet balsamic tilapia with brown rice and honey roasted acorn squash.
Common Mistakes
