Are you looking for big returns for your investment portfolio? If you answered yes to that, I have good news.

The two ASX 200 blue chip shares listed below have been tipped to rise approximately 30% over the next 12 months.

Here's why analysts are bullish on these names:

James Hardie Industries plc (ASX: JHX)

The team at Bell Potter thinks that James Hardie could be an ASX 200 blue chip share to buy now.

It is a global building materials company and the largest global manufacturer of fibre cement products.

Bell Potter likes the company due to the structural shift towards fibre cement in the United States, which it expects to support an earnings expansion. It said:

In our view, James Hardie is poised for continued earnings expansion, driven by the structural shift towards fibre cement in the US. Households in the US continue to shift to fibre cement cladding from vinyl/timber, providing a multi- year runway for JHX's revenue and profit growth.

With a strong market position, premium brand, and pricing power, JHX is poised to capitalise on structural growth in the fibre cement market and cyclical tailwinds from potential rate cuts.

The broker has a buy rating and $64.00 price target on its shares. Based on its current share price of $49.77, this implies potential upside of almost 30% for investors.

Woodside Energy Group Ltd (ASX: WDS)

Another ASX 200 blue chip share that could generate big returns for investors in 2025 is Woodside Energy.

It is a global energy giant that provides the energy that the world needs to heat and cool homes, keep lights on, and support industry.

The team at Morgans believes its shares are undervalued at present. It recently commented:

The tide is certainly out in terms of investor sentiment on WDS. Despite Brent oil trading in line with our long-term forecast, WDS' share price implies a near cycle-low oil price level. We do not see this as capable of being explained by WDS' growth profile (comfortably funded) or risks around non-core assets such as Browse.

While the share price performance has been disappointing, supported by a strong balance sheet and high margins, we see WDS investors as capable of being patient. Investment view: We maintain an ADD recommendation believing WDS offers attractive long-term value.

Morgans has an add rating and $33.00 price target on its shares. Based on the current Woodside share price of $25.20, this implies potential upside of 31% for investors. The broker also expects a generous ~6% dividend yield in FY 2025.
